Statement from the Chief Public Health Officer of Canada on June 10, 2021

On June 10, 2021, Dr. Theresa Tam, Canada’s Chief Public Health Officer, issued the following statement on COVID-19.

June 10, 2021 | Ottawa, ON | Public Health Agency of Canada 

As summer quickly approaches, several areas across the country are already experiencing increasing temperatures. Extended periods of extreme heat and humidity can take a toll on our well-being and put us at risk for heat-related illnesses, such as heat stroke, heat rash, heat fainting and in the most severe cases death.

Very hot weather can make pre-existing conditions and breathing problems worse. Those most at risk from the harmful effects of heat are seniors, infants and young children, some people with chronic illnesses or disabilities, people experiencing homelessness, those who live in poorly ventilated households, and people who work or are active outdoors. During extreme heat, be aware of the signs of heat-related illness and pay attention to how you and those around you are feeling. Check in on grandparents, neighbours, friends and community members at risk from extreme heat to make sure they are keeping cool. 

As people across Canada embrace the summer, it’s important to be prepared and take steps to stay healthy in the heat, while being mindful of COVID-19 precautions in place. High heat and humidity can make wearing a mask difficult. When outdoors, practice physical distancing whenever possible and reserve wearing a mask for use indoors or when physical distancing is not possible. Staying hydrated, avoiding direct sun, wearing loose-fitting, light-coloured clothing, taking a cool shower or bath, and avoiding strenuous activity outdoors are some of the ways to stay cool and healthy. Canada’s Weather app and your local news and public health websites are great resources for heat warnings and getting ideas for cooling off.

As COVID-19 activity continues in Canada, we are tracking a range of epidemiological indicators to monitor where the disease is most active, where it is spreading and how it is impacting the health of Canadians and public health, laboratory and healthcare capacity. At the same time, the Public Health Agency of Canada is providing Canadians with regular updates on COVID-19 vaccines administered, vaccination coverage and ongoing monitoring of vaccine safety across the country. The following is the latest summary on national numbers and trends, and the actions we all need to be taking to reduce infection rates, while vaccination programs expand, including acceleration of second dose programs, to better protect people and communities across the country.

Since the start of the pandemic, there have been 1,396,798 cases of COVID-19 and 25,843 deaths reported in Canada; these cumulative numbers tell us about the overall burden of COVID-19 illness to date. They also tell us, together with results of serological studies, that a large majority of Canadians remain susceptible to COVID-19. However, as vaccination programs expand at an accelerated pace, there is increasing optimism that widespread, stronger and longer lasting immunity can be achieved by fully vaccinating a high proportion of Canadians over the coming weeks and months.

As immunity is still building up across the population, public health measures and individual precautions remain crucial for COVID-19 control. Thanks to measures in place in heavily affected areas, the strong and steady declines in disease trends continues. The latest national-level data show a continued downward trend in disease activity with an average of 1,646 cases reported daily during the latest 7 day period (June 3-9), down 33% compared to the week prior and down 81% compared to the peak of the third wave. Until vaccine coverage is sufficiently high to impact disease transmission more broadly in the community, we must sustain a high degree of caution to drive infection rates down to a low, manageable level, and not ease restrictions too soon or too quickly where infection rates are high.

With the considerable decline in infection rates nationally, the overall number of people experiencing severe and critical illness is also steadily declining. Provincial and territorial data indicate that an average of 1900 people with COVID-19 were being treated in Canadian hospitals each day during the most recent 7-day period (June 3-9), which is 22% fewer than last week. This includes, on average 817 people who were being treated in intensive care units (ICU), 21% fewer than last week. Likewise, the latest 7-day average of 31 deaths reported daily (June 3-9) is continuing to decline, showing a 13% decrease compared to the week prior.

Overall, variants of concern (VOCs) represent the majority of recently reported COVID-19 cases across the country. Four VOCs (B.1.1.7 (Alpha), B.1.351 (Beta), P.1 (Gamma), and B.1.617, which includes B.1.617.2 (Delta)) have been detected in most provinces and territories, however, the Alpha variant continues to account for the majority of genetically sequenced variants in Canada. As Canada continues to monitor and assess genetic variants of the SARS-CoV-2 virus, including impacts in the Canadian context, we know that vaccination, in combination with public health and individual measures, are working to reduce spread of COVID-19.

As vaccine eligibility continues to expand, Canadians are encouraged to get vaccinated and support others to get vaccinated as soon as they are able. As well, with provinces and territories accelerating second dose programs, those who are eligible are urged to get fully vaccinated with a second dose of two dose series COVID-19 vaccines approved for use in Canada. The second immune-boosting dose, substantially lowers our personal risk of infection and serious harms, provides stronger protection against certain variants of concern, including the Delta variant, and may make immunity last longer. Canadians are reminded that it is safe and effective to receive one vaccine product for your first dose and a different vaccine product for your second dose to complete your two-dose vaccine series for optimal protection from COVID-19.

However, regardless of our vaccination status while COVID-19 is still circulating, it is important to remain vigilant, continue following local public health advice, and consistently maintain individual practices that keep us and our families safer, even as the positive impacts of COVID-19 vaccines are building: stay home/self-isolate if you have any symptoms, think about the risks and reduce non-essential activities and outings to a minimum, avoid all non-essential travel, and maintain individual protective practices of physical distancing, hand, cough and surface hygiene and wearing a well-fitted and properly worn face mask as appropriate (including in shared spaces, indoors or outdoors, with people from outside of your immediate household).

For more information regarding the risks and benefits of vaccination, I encourage Canadians to reach out to your local public health authorities, healthcare provider, or other trusted and credible sources, such as Canada.ca and Immunize.ca. Working together, Health Canada, the Public Health Agency of Canada, the National Advisory Committee on Immunization, Canada’s Chief Medical Officers of Health and other health professionals across the country are closely monitoring vaccine safety, effectiveness and optimal use to adapt approaches. As the science and situation evolves, we are committed to providing clear and evidence-informed guidance in order to keep everyone in Canada safe and healthy.

Canadians can also go the extra mile by sharing credible information on COVID-19 risks and prevention practices and measures to reduce COVID-19 in communities.
