In 2023 Canada experienced an unprecedented wildfire season, where larger areas of the country were impacted with greater severity.Footnote 1 What was seen in 2023 was a continuation of the trend of longer wildfire seasons, with more frequent and extreme fire behaviour.Footnote 2Footnote 3 It is expected that wildfires will continue to occur throughout the coming years, and modeling suggests that by 2100 the overall fire occurrence could increase by as much as 75%.Footnote 4Footnote 5Footnote 6Footnote 7 In Canada, the wildfire season typically runs from early April to late October, however for 2024, Alberta announced that their wildfire season will start 10 days earlier.Footnote 8
Wildfires are a key public health issue because they are widespread, the health impacts are severe, and inequitably distributed.Footnote 9 In addition to their impact on the physical and mental health of populations, the impacts of wildfires are experienced differently across population groups based on their intersecting social determinants of health (SDOH) such as age, geography, gender, and income.Footnote 10 An important lesson learned from the COVID-19 pandemic was the inequitable impacts of emergencies on populations already in situations of vulnerabilityFootnote 9Footnote 11 and the creation of new inequities by the emergency.
Systemic inequities drive exposure, sensitivity, and adaptive capacity to climate hazards as different individual factors and SDOH influence people's climate vulnerability. Therefore, understanding how different population groups, especially those already in situations of vulnerability, experience and are affected by wildfires ensures that health equity considerations are prioritized and embedded in emergency preparedness and response, and in public health action on climate change.Footnote 9Footnote 11 By addressing societal inequities and vulnerabilities, public health outcomes can be improved for all.
Sex and Gender Based Analysis Plus (SGBA Plus)
Sex- and Gender-Based Analysis Plus (SGBA Plus) is a Government of Canada priority and supports the advancement of health equity considerations in all policies, programs, and practices across the Health PortfolioFootnote a. SGBA Plus considers how multiple social determinants of health such as race, age, income, sexual orientation, geographic location, and socioeconomic status intersect to influence health outcomes. The intersections between these identities occur within a context of connected systems and structures of power (e.g., laws, policies, governments) to shape experiences. SGBA Plus is an intersectional analytical approach that examines how various intersecting structural and social determinants of health (SDOH) influence equitable health outcomes.Footnote 12
The public health consequences of wildfires are multifaceted and require an intersectional approach to understand their differential impact across diverse population groups.
This rapid review explored the evidence of the disproportionate health impacts of wildfires on certain communities and populations based on intersecting structural and social determinants of health. As wildfires are an emerging public health issue we wanted to generate a rapid review to support those working on a range of related public health and public policy interventions. The suggestions on key health equity-related considerations related to wildfires and wildfire smoke are based on this review and are provided for consideration by those planning for and responding to wildfire-related events.
Applying an intersectional approach to wildfires in Canada
Health outcomes
Increased wildfire activity and intensity, increase the risk for adverse physical and mental health outcomes for people living in Canada. Key implications of wildfires also include displacement of communities, destruction of ecosystems, and compromised air quality, all of which have long-term impacts on health outcomes.Footnote 14 Wildfires and wildfire smoke can trigger a range of negative physical and mental health outcomes.Footnote 14Footnote 15 The wide-ranging evidence to support the differential health impacts of wildfires and wildfire smoke on diverse population groups is summarized below.
Physical health
Wildfires impact physical health primarily due to fire, smoke, and heat.Footnote 15Footnote 16Footnote 17 The main impacts were primarily respiratory and cardiovascular morbidity and ophthalmic problems.Footnote 15 In addition, severe burns resulting from direct contact with the fire require specialized care and carry a risk of multi–organ complications.Footnote 15 Finally, there are the wider health implications that result from the pollution of the air, water, and land after a wildfire.Footnote 15Footnote 17 Toxic chemicals from wildfires can be deposited on vegetation and washed into bodies of water contaminating them, and impacting water potability and the health of aquatic species.Footnote 18
Exposure to wildfire smoke is strongly associated with an increased risk of all-cause mortality, followed by respiratory and cardiovascular mortality, adverse respiratory effects, such as exacerbations of asthma and chronic obstructive pulmonary disease (COPD and an increased risk of reproductive and developmental effects (for example, low birth weight).Footnote 19
Mental health
There is evidence of increased rates of mental health impacts (for example, anxiety, depression, and post-traumatic stress disorder) in communities impacted by wildfires, which have been linked with both wildfire events and wildfire smoke.Footnote 14Footnote 20Footnote 21 Studies also demonstrate a strong correlation between negative mental health outcomes—such as major depressive disorder (MDD), post-traumatic stress disorder (PTSD), and generalized anxiety disorder (GAD) — and experiences of wildfires among adult and youth populations.Footnote 22Footnote 23Footnote 24Footnote 25. This association was more prominent for people with pre-existing mental health conditionsFootnote 22Footnote 23Footnote 25 and for those who experienced the disaster in greater proximity through witnessing homes burning, having their home destroyed, or experiencing a relocation.Footnote 22
Amongst Grade 7-12 students impacted by the Fort McMurray wildfire, scores for depression symptoms, suicidal thinking, and tobacco use were higher than controls 18 months after the fire.Footnote 26 These symptoms unfortunately didn't decrease with time, and three and half years after the Fort McMurray wildfire the mental health of these students had further declined.Footnote 27
The differential impact of wildfires due to social and structural determinants of health
Geographic location/isolation
While wildfires have become increasingly widespread in recent years, there are specific regions in Canada that are disproportionately affected. 2023 was the worst wildfireFootnote 28 season to date with an estimated 2,619 fires as of June 19, 2023.Footnote 16 Affected provinces include British Columbia, Alberta, Ontario, Quebec, and Nova Scotia.
Geographic location, specifically the distinction between rural and urban centres, has an impact on health outcomes and contributes to disproportionate experiences in public health issues. Rural communities face unique impacts in response to wildfires as they do not always have the infrastructure to readily handle evacuation needs, may face challenges with communication, and experience issues with obtaining support from external parties.Footnote 29 A qualitative study exploring public health practitioners' perceptions of responses to wildfire smoke events across Canada, demonstrated that practitioners felt remote communities often did not have the resources and infrastructure available to have designated community clean-air shelters or other indoor spaces that would be appropriate for prolonged stay during smoke events.Footnote 30
A study conducted in four rural sites in Alberta, Saskatchewan, and British Columbia to understand the impact of wildfires on rural communities, found that rural settings generally did not have the infrastructure for available personnel to respond to disasters as urban areas do.Footnote 31 Wildfires also posed specific issues for ranches and farms, as demonstrated by the McLure fire where relocation of animals with adequate feed and water was difficult. This led some livestock owners to opt to stay with their livestock which placed them at heightened risk and made them vulnerable to injury and death.Footnote 31 Issues with communication between authorities and the public also made it difficult for community members to understand events that were occurring, which added to their individual stress levels and hindered recovery.Footnote 31 In general, rural communities are often well-connected and familiar with their neighbors; therefore when large groups of external personnel enter the community to respond to the wildfires, it can be intimidating, especially during a period of recovery.Footnote 31
Indigenous identity
It is estimated that First Nations communities make up 42% of evacuations due to wildfires but only make up 5% of people living in Canada.Footnote 1 As of July 2023, 106 wildfires affected 93 First Nations, leading to 64 evacuations impacting nearly 25,000 people.Footnote 32 Indigenous communities disproportionately experience both adverse mental health and physical health outcomes due to wildfires. Recent wildfires have displaced many remote and Northern Indigenous communities, leaving many without the ability to participate in their traditional ways of life and cultural practices. The impact of wildfires on Indigenous Peoples is influenced by colonialism,Footnote 33 and has forced many Indigenous Peoples to live in isolation or in communities that are isolated from the rest of society. Their geographic isolation makes it difficult to access basic goods, services, and other resources that are necessary for mitigating and building resilience against the impacts of wildfires. In addition, Indigenous communities often depend on the land for food, water, recreation, and cultural practices. Therefore, wildfires disrupt Indigenous ways of life and threaten important cultural activities, such as hunting, fishing, harvesting, and gathering.Footnote 32 Evacuation can also result in the disruption of traditional and subsistence activities, and the collection and use of traditional healing medicines and foods, which can negatively impact mental and spiritual well-being. After a wildfire, residents who return home may face financial, health, and social stresses associated with the loss of personal property and having to rebuild homes and community. In addition, they may return to a devastated landscape that serves as a daily reminder of their loss. This can lead to solastalgia, a form of mental or existential distress caused by environmental change.Footnote 34
Furthermore, Indigenous communities are often excluded from emergency preparedness and relief measuresFootnote 35, that undermine Indigenous rights to self-determination and autonomy. For example, Indigenous Peoples are often left out of decision-making processes regarding forest management before and after wildfire events, despite being the traditional keepers and stewards of the land.Footnote 32 In addition, it is only recently that the role of Indigenous Peoples's traditional fire stewardship practices has been recognized and supported.Footnote 36Footnote 37 Recognizing Indigenous sovereignty is crucial for ensuring cultural preservation and the protection of ancestral lands.
In 2014, a retrospective cohort study examining the cardiorespiratory outcomes of wildfire smoke in the Northwest Territories found that among residents in and around Yellowknife, Dene had higher Emergency Room visits for asthma, and pneumonia rates were higher among Inuit compared to non-Indigenous residents.Footnote 38
The socio-cultural/economic conditions that impacted Indigenous Peoples the most after a wildfire evacuation were primarily the lack of both culturally sensitive services and access to funding. Following the 2016 Horse River wildfire in Northern Alberta, a qualitative study demonstrated that service providers felt the delivery of mental health and wellness services to rural and remote Indigenous communities was inconsistent prior to the wildfire and exacerbated after the wildfire.Footnote 39 They also found that services lacked cultural appropriateness, were not adequately resourced, and overlooked long-term recovery. Of those who experienced the 2014 Northwest Territories wildfire season, First Nations interviewees experienced challenges to their food security and livelihoods due to restricted ability to engage in traditional land-based activities and reduction to sources of country foods, limiting employment and income sources (for example, hunting, foraging, fishing).Footnote 40
These findings were reinforced by a report from the House of Commons Standing Committee on Indigenous and Northern Affairs that examined the impacts of the 2017 wildfires on First Nations communities across Canada.Footnote 41 The report found that many Indigenous Peoples also faced additional economic challenges during evacuations and recovery phases. While they were eligible for reimbursement of funds utilized during an emergency through Indigenous Service programs; many experienced difficulties claiming these expenses due to challenges with applying for reimbursement and not always receiving the full amount of a claim.Footnote 41Footnote 42
For First Nations evacuees, there was a lack of space for the practice of traditional activities and preparation of traditional foods, as well as a lack of mental health resources for those being temporarily housed in shelters.Footnote 41
Finally it was noted that the evacuation measures conducted in Indigenous communities served as traumatic reminders of being taken away to residential schools and/or the Sixties Scoop as some were forced onto buses and separated from familyFootnote 41.
A community-based qualitative case study examining how residents of Sandy Lake First Nation were impacted by the 2011 wildfire evacuation found that a lack of pre-event preparedness resulted in some Elders with medical conditions being evacuated without a caregiver and families were separated and displaced during evacuation operations.Footnote 43 During evacuations, additional challenges included transportation issues that prevented large families from being evacuated together in one vehicle and language barriers that caused stress for non-English speakers.Footnote 42 Finally, during the 2011 Alberta wildfire, members of the Whitefish Lake First Nation 459 who experienced poverty faced complications as they did not have extra funds to pay upfront for expenses incurred by the evacuation.Footnote 42
Race and ethnicity
Environmental racism refers to "environmental policies, acts, and decisions that, intentionally or not, disproportionately disadvantage racialized individuals, groups, and communities."Footnote 44 In terms of Canada's wildfires, racialized communities—including Indigenous populations (see section on "Indigenous Identity")—are inequitably impacted by displacement, loss of homes, disruption of traditional livelihoods, and adverse health effects from smoke inhalation.Footnote 33 In Canada, racialized populations are more likely to live with low-income and poor housing conditions compared to the general population, which can exacerbate the impacts of damages incurred by wildfires.Footnote 45Footnote 46 In addition, historical land use policies have placed racialized populations at higher risk of exposure to environmental threats, including wildfires.Footnote 47Footnote 48
There is a paucity of Canadian literature that examined health outcomes among racialized populations. However, a study that examined the mental health service utilization rates among evacuees during the Fort McMurray wildfire found that racialized evacuees were less likely to receive mental health services.Footnote r9 This finding was supported by studies conducted in the United States that demonstrate the disproportionate impact on racialized communities due to differential exposure and adaptive capacities.Footnote 50Footnote 51
Sex and gender
Women are disproportionately impacted by climate-related threats due to their long-standing social roles as caretakers, vulnerability to gender-based violence, and pre-existing mental health challenges.Footnote 52Footnote 53Footnote 54 Studies found that women are more vulnerable to climate-related events due to gender inequalities, that lead to having lower income, greater caregiving responsibilities, mobility constraints, and less access to financial or life-sustaining resources.Footnote 55 (see section on "Family and Pregnancy")
Results from several studies conducted after the 2016 Fort McMurray wildfire found that women experience worse mental health impacts in comparison to men. This was also noted for people who did not identify within the gender binary. Among Grade 7-12 students, those who identified as femaleFootnote b exhibited higher mental health symptom scores, higher rates of probable diagnosis of MDD, PTSD, and GAD, and lower scores for self-esteem, quality of life, and resilience in comparison to their male-identifying students.Footnote 27 Students who identified with another gender or preferred not to state their gender identity exhibited worse mental health outcomes compared to both their female- and male-identifying counterparts.
When the health outcomes of evacuated workersFootnote 57 and college studentsFootnote 58 were examined, a greater proportion of women compared to men experienced symptoms of MDD and GAD, as well as PTSD. Gender was also a statistically significant predictor amongst evacuated adults, with women being more likely than men to seekFootnote c, and require mental health services.Footnote 49Footnote 59 Despite the limited amount of evidence, these studies point to the importance of considering the distinct needs and barriers experienced by gender-diverse populations during wildfires and other climate-related events.
Age
Age is associated with physical and mental health outcomes related to wildfires. It was observed that non-modifiable biological factors related to age such as physical capacity, immune function, and social and structural determinants intersect with age to exacerbate or mitigate risk factors and adverse health outcomes. Social support was observed to be important for outcomes in older adults. Those who had social support at the community and individual level were more likely to survive wildfires.Footnote 60 A reliable and supportive social network also provides critical psychological and emotional support for older adults during wildfire evacuations.Footnote 60
People younger than 25 years of age generally seem to have worse mental health outcomes than those above 40 years of age. A cross-sectional study examining predictors of resilienceFootnote d in residents, five years after the 2016 Fort McMurray wildfire found that those younger than 25 years old were more likely to have low resilience compared to those older than 40 years.Footnote 61 Other cross-sectional studies investigating mental health impacts after the same wildfire found that those younger than 40 years were more likely to develop MDDFootnote 25 and those 25 years or younger were more likely to present with MDD, GAD, and PTSD.Footnote 58
Socioeconomic status
Socioeconomic status (SES) and education are highly interconnected social determinants of health associated with mental health outcomes. Individuals with a lower SES often experience increased stress due to financial instability and low access to resources, which can impact their mental well-being.Footnote 62 Emergencies, such as wildfires and related evacuations may exacerbate these stressors and their impacts on mental health outcomes. Additionally, a lack of socio-economic resources could also impact access to the services and resources required for emergency prevention, mitigation, and recovery.Footnote 63 Among evacuees from the 2016 Fort McMurray wildfire, it was observed that having had financial difficulties due to economic decline in the city before the wildfire was a predictor of developing PTSD, MDD, GAD, insomnia, and substance use.Footnote 23 In addition, the depression scores of participants who experienced financial loss from lack of work were higher than those who did not experience financial loss.Footnote 57 A year after the 2016 Fort McMurray wildfire, participants holding post-secondary education were more likely to receive information and counseling/psychotherapy than those with secondary education or less.Footnote 49
Housing
Poor housing conditions exacerbate exposure to wildfire smoke and increase the risk of adverse mental and physical health outcomes. Housing is a structural determinant of health that intersects with many other social and systemic factors, including SES, race, Indigenous identity, geography, and disability. For instance, Indigenous Peoples were almost twice as likely to live in crowded housing, and three times more likely to live in a dwelling in need of major repairs, in comparison to the non-Indigenous population in Canada.Footnote 64 People living in accommodations without air conditioning or proper ventilation, in shelters, on the street, or in their vehicles were more exposed to wildfire smoke; which is associated with cardiovascular and respiratory diseases.Footnote 65 People who are unhoused or living in housing with poor ventilation or ineffective cooling systems are also particularly susceptible to adverse mental health outcomes.Footnote 66 Finally, those living in precarious housing have fewer opportunities to engage in mitigation strategies against wildfires-related health impacts.Footnote 66 It has to be recognized that although evacuation centers are available to all individuals, stigma and mistrust of authorities can present barriers to access for some.Footnote 67
Occupation
In response to wildfires, people in certain occupations experience greater exposure to wildfire smoke and are therefore at an increased risk of negative health impacts, especially the heightened risk of respiratory morbidity.
When the health effects of wildfire smoke exposure on RCMP officers deployed during the 2016 Fort McMurray were examined, it was found that they were exposed to extremely high levels of wildfire-related air pollutants. They also presented with higher COPD assessment scores and prevalence of asthma than the general population.Footnote 68 Firefighters deployed during wildfire events exhibited ongoing respiratory problems with decreased diffusing capacity of the lung, new onset asthma, hyperactivity with bronchial wall thickening compared to community controlsFootnote 69 and measurable inflammatory responses in the lung which were associated with upper and lower respiratory tract infections.Footnote 70 Occupational groups (for example, firefighters) that work directly to address wildfire emergencies may also experience negative mental health outcomes. A cohort of firefighters deployed during the 2016 Fort McMurray Wildfire had high rates of mental health conditionsFootnote 71 with prevalence estimates for PTSD, anxiety disorders, and depressive disorders at 21.4%, 15.8%, and 14.3% respectively. Importantly the PTSD prevalence rates found in this cohort were higher than previously reported estimates in firefighters (13.5%) not exposed to a major disaster in Canada.Footnote 71
Family and pregnancy
Parents have increased stress and responsibilities in dealing with the aftermath of potential material losses, reorganization of daily life, and concerns about children's safety.Footnote 72 Children may be less cared for as parents have less time for them when addressing the damage and change caused by wildfires. As well, pregnant women and pregnant people experience difficulties with mobility and may be unable to continue normal breastfeeding practices due to disruptions caused by wildfires. Given the intersection of family and pregnancy with gender, women tend to act as caretakers and are likely more impacted in these roles during wildfires (see section on Sex and Gender). The 2011 wildfires, in Slave Lake Alberta affected the everyday life of children as schools and children's clubs were not re-opened after the wildfires ceased and parents often focused on dealing with logistic considerations, leaving them with less time to tend to their children's needs.Footnote 73 Public health practitioners also reported receiving concerns from families with children about the need to keep children indoors to limit smoke exposure, which also limited their children's physical activity.Footnote 30 During and after the Fort McMurray wildfire, it was found that pregnancy was a barrier during evacuations as pregnant women and pregnant people had limited physical capabilities, needed washroom facilities, and experienced fatigue.Footnote 74 Pregnant women and pregnant people also experienced varied stress responses, lack of sleep, and some experienced pregnancy complications (for example, intrauterine growth restriction, preterm births) that were potentially related to heightened stress levels.Footnote 74 Finally, during the Fort McMurray wildfire evacuation, there was a decrease in breastfeeding and increased usage of infant formula.Footnote 75
Faith communities
Faith communities can experience specific barriers and experience certain disruptions when evacuated due to wildfires. It is important to acknowledge and attempt to support faith communities impacted by wildfire response activities. Indigenous Peoples spirituality is land-based so there is a specific and deep level of distress associated with the destruction of the land and disruption of traditional land-based activities as a result of wildfires and the resulting evacuations.Footnote 76 During the 2016 Wildfire, 10% of Fort McMurray's population was Muslim.Footnote 77 They experienced a lack of privacy when needing to stay in group-lodging facilities, a lack of appropriate clothes and food, and additional considerations for spirituality and prayer.Footnote 78 While these observations are limited to Muslim communities and Indigenous Peoples, it is important to recognize that wildfires may negatively impact the faith practices of several other religious communities.
Wildfire smoke
Populations in close proximity to and at great distances from wildfire events are at risk of wildfire smoke, as the air pollutants can be transported thousands of kilometers away.Footnote 79 The health effects of wildfire smoke are an active and growing area of research. To support and inform guidance and actions related to wildfire smoke, Health Canada conducted a weight-of-evidence review of the health outcomes associated with exposure to wildfire smoke based on existing systematic reviews.Footnote 19 There is consistent and strong evidence in the literature that wildfire smoke is associated with an increased risk of premature mortality and adverse respiratory effects (for example, exacerbation of asthma and COPD). There is also some evidence of an increased risk of cardiovascular mortality and morbidity. Additionally, there is some evidence of an association between wildfire smoke exposure and reproductive and developmental effects (for example, low birth weight). For other reproductive and developmental effects and mental health impacts, more research is needed to differentiate the effects attributable to wildfire smoke vs wildfire events.
The literature base also identified some groups that may be disproportionately impacted by wildfires and wildfire smoke, including seniors (65 years and older), children, women, pregnant women and people, Indigenous populations, people living in remote areas, people with pre-existing health conditions, people with lower socio-economic status (SES), and wildland firefighters.Footnote 19 Various factors contribute to these disproportionate risks, including biological and physiological differences due to life stage and/or presence of a comorbidity, and increased likelihood of exposure to wildfires due to location or occupation. Specifically from North American studies, increased risks of non-fatal respiratory outcomes were noted for children, seniors, women, and those with lower SES.
Equity-related considerations during wildfires
The results of this rapid review have highlighted some key health equity-related considerations related to wildfires and wildfire smoke that could be considered by those planning for and responding to these eventsFootnote e.
Interventions and policies could consider the benefit of:
- Increased access to effective and long-term mental health supports for communities affected by wildfires.Footnote 23Footnote 26Footnote 27
- Routine health assessments and adequate preventative measures (for example, supplying personally fitted respiratory protections) for those working in occupations regularly deployed during wildfires to monitor and mitigate health impacts.Footnote 68
- Evacuation procedures and activities tailored to the distinct needs and experiences of diverse populations. For example:
- Accessible materials for preparedness and response (for example, flyers and handouts) and availability of inclusive and low-barrier evacuation spaces.Footnote 67
- Consideration of privacy and space needs for families and for those who are breastfeeding.
- Considering the cultural needs of faith communities and Indigenous Peoples during evacuations and developing community-based plan that reflect this consideration such as the provision of culturally appropriate foods.
- Consultation with community members after severe wildfire events to inform future planning and response to wildfires in order to incorporate local knowledge, context, and lived experience.Footnote 40
- Relocating evacuees together to offer opportunities to strengthen cohesion, altruism, and support within the community.Footnote 80
Meaningful engagement with and co-developing or adapting existing wildfire prevention, preparedness, response, and recovery resources and activities alongside diverse populations/community groups:
- Financial support and other resources for outreach, education and prevention initiatives.Footnote 42
- Wildfire management and response that integrates Indigenous knowledges in partnership with diverse First Nations, Inuit, and Métis communities.
- Increased involvement of Indigenous communities in wildfire response and recovery, is critical for restoring culturally significant food sources, plants, and other land-based ties.Footnote 81
Examine the value of mobile clinics, as they play a critical role in monitoring and promoting the health of people impacted by wildfires:
- Mobile clinics improve access to healthcare for underserved communities, people experiencing homelessness, and those without health insurance in rural and remote areas.Footnote 82
- Specifically, mobile clinics provide essential primary care services, as well as health education, mental health assessments, vaccinations, and screenings that would otherwise be missed when populations are displaced by climate disasters.Footnote 82
Limitations
While the present rapid review attempts to explore the impacts on diverse population groups in Canada, further evidence is necessary to gain a more robust understanding of the extent of the impacts of wildfires on diverse population groups living in Canada.
