The Yukon’s experience with coronavirus disease 2019 (COVID-19) has been an interesting one; the territory successfully implemented travel restrictions to limit importing the virus and rolled out vaccines quickly compared to most Canadian jurisdictions. However, the Yukon’s first wave of COVID-19 in June and July 2021 overwhelmed the healthcare system due to widespread transmission in unvaccinated children, youth and adults, despite high vaccination uptake overall and mandatory masking. This experience highlights the importance of continued support for public vaccination programs, widespread vaccine uptake in paediatric populations, and the judicious relaxation of non-pharmaceutical interventions in all Canadian jurisdictions as they reopen while more contagious variants emerge.


The coronavirus disease 2019 (COVID-19) trajectory across Canada has been an uneven one, and the Yukon Territory, Canada is an interesting case. From March 22, 2020, to June 1, 2021, there were 62 cases and two deaths due to COVID-19 in the YukonFootnote 1. An important feature of the Yukon’s public health strategy was implementing travel restrictions, where, similar to the Atlantic provinces, travellers entering the territory had to self-isolate for 14 days. The Yukon has a small, sparse population and, thanks to few access points, was able to enforce travel restrictions to limit imported cases. However, in June and July 2021, shortly after lifting some restrictions, the Yukon experienced its first wave of COVID-19 with community transmission, despite having the highest vaccination rate in Canada by the end of MayFootnote 2. From June 1 to August 2, 2021, Yukon reported 541 new cases of COVID-19 as part of three distinct outbreaks and six deaths in a population of about 42,000Footnote 3. Most people who became ill were unvaccinated Footnote 4, with only 14% of cases fully vaccinated, and none of the COVID-19 patients who died were fully vaccinatedFootnote 1. On July 28, 2020, the government reported that a total of 52 people were hospitalized during this wave; of that group, 43 were unvaccinated or only partially vaccinated. Fourteen cases, 11 of whom were unvaccinated, were in critical condition and were medically evacuated to larger centersFootnote 5. In this commentary, we present the Yukon’s experience with the COVID-19 pandemic and highlight lessons learned from its late wave of COVID-19 in June and July 2021.


The Yukon is Canada’s second smallest jurisdiction by population. About 75% of the population lives in Whitehorse, the territory’s capital, and the remainder in 15 smaller communitiesFootnote 3. There are three hospitals. Whitehorse General, the largest, has 56 beds, a range of services including a four-bed intensive care unit, and accommodates 32,000 emergency visits and 3,703 admissions per year. Two community hospitals in Watson Lake and Dawson City have emergency services and six bed inpatient units each, with 112 and 80 admissions per year and 2,627 and 2,812 emergency visits annually, respectivelyFootnote 6. This overall hospital capacity is historically adequate for the population; however, medical evacuation or medical travel is often required for high acuity cases or those requiring specialist careFootnote 7. This leaves the Yukon at higher risk during the COVID-19 pandemic, as a significant outbreak could overwhelm healthcare capacity. If cases are also surging in other jurisdictions, medical evacuation to larger centres, such as Vancouver or EdmontonFootnote 8, may not be possible.

Following devolution in 2003, the Yukon territorial government assumed responsibility for public health, along with other provincial powers, from the Canadian federal government. Eleven of the 14 Yukon First Nations are self-governing and able to draw responsibilities from the territorial government, including some related to health, after they pass their own legislationFootnote 9. In the 2016 census, approximately 23% of the population identified as having Indigenous ancestryFootnote 10. The Yukon’s economy is largely based on government; Yukon depends heavily on federal transfersFootnote 11. Mining, services and tourism are also important drivers. Because of self-isolation requirements following travel, tourism decreased by 25% in the first quarter of 2020 compared to 2019Footnote 12. The unique demographic, economic and institutional context of the Yukon influenced the pandemic response.

Pandemic response

The Government of Yukon, enabled by its status as a “proto-province”Footnote 13, lead the pandemic response; the Council of Yukon First Nations, representing Yukon First Nations governments, also played a role in coordination and communication. Early on, the Yukon government enacted typical public health restrictions such as restricting gatherings, closing bars and personal care services, and suspending healthcare services. The first cases of COVID-19 in Yukon were announced on March 22, 2020 (Figure 1), after restrictions were in place. Restricting out-of-territory travel as of March 22, 2020, limited importing cases into the Yukon: a 14-day self-isolation was required for all travellers entering the territory. Yukoners were requested to limit their rural community travel, and some First Nations governments set up check points into their traditional territories. A border control measures order was issued on April 2, 2020, to enforce self-isolation requirements at border entry pointsFootnote 14. A travel “bubble” with British Columbia was established on July 1, 2020, allowing travel between the two jurisdictions without self-isolation; however, the bubble ended on November 20, 2020, after cases began increasing in the YukonFootnote 15. These travel restrictions effectively prevented a major COVID-19 outbreak in the Yukon for the first year of the pandemic. Mandatory masks for Yukoners over the age of five years in public places were instituted on December 1, 2020—one of the last Canadian jurisdictions to mandate mask-wearingFootnote 16 since there had been such limited COVID-19 cases present in the Yukon (Figure 1).

COVID-19, coronavirus disease 2019

The first doses of the Moderna COVID-19 vaccine were administered in Yukon on January 4, 2021, earlier than Canadian provinces because of the territory’s limited hospital capacity. Mobile vaccination teams were deployed to communities outside of WhitehorseFootnote 17. As of May 22, 2021, 55.22% of the total population was fully vaccinatedFootnote 2. Self-isolation requirements were lifted on May 25, 2021 for fully vaccinated domestic travellers, or for fully vaccinated Yukoners returning after domestic travel (Figure 1)Footnote 18. This announcement created an additional incentive for vaccination.

Shortly after self-isolation requirements for travellers were lifted, an outbreak of the Gamma variant was declared on June 13, 2021 (Figure 1)Footnote 19. Transmission occurred at secondary school graduation parties, barsFootnote 20, daycares and the Whitehorse Emergency Shelter; transmission was mostly in unvaccinated adults, youth and childrenFootnote 4. Graduation season facilitated disease transmission because graduates and family members travelled between communities, and attended both informal, unmasked, celebrations and larger, organized gatherings with COVID-19 measures in place. In fact, the outbreak can be linked back to a single infected individual who attended a large partyFootnote 20. On July 14, 2021, 240 of 414 cases had been confirmed as the Gamma variantFootnote 21.

Yukon’s Chief Medical Officer of Health encouraged those not yet vaccinated to book appointments and for all Yukoners to “stick to six” people for gatherings, but lowered formal gathering limits to 10 indoors with masks and 20 outdoorsFootnote 22. Other public health measures included cancelling some graduation eventsFootnote 23, urging parents to keep children home from daycare Footnote 22 and increased restrictions by the Yukon Hospital CorporationFootnote 4. Cases were present in most Yukon communities. Many Yukon First Nations requested that travellers refrain from visiting. Contact tracing, testing and vaccination teams were at capacity; the Premier requested additional support from the federal governmentFootnote 22. On July 28, 2021, no new cases were reported for the first time since June 5, 2021; as of July 31, 2021, 68.63% of the total population was fully vaccinated (Figure 1) Footnote 2. All remaining public health restrictions were lifted on August 4, 2021, including the requirement for travellers who were not vaccinated to self-isolate and mandatory indoor maskingFootnote 24; this decision received some public criticism, including from the Kwanlin Dün First Nation’s chiefFootnote 25.


Some insights can be gleaned from Yukon’s experience with COVID-19. The first is the importance of mitigating case importations through self-isolation requirements for travellers entering a region. To illustrate, modeling studies for Newfoundland demonstrated that without introducing a self-isolation requirement for travellers, there would have been 12.4 times more COVID-19 cases in the early weeks of the pandemicFootnote 26. Managing case importations is critical in small jurisdictions with limited hospital capacity, such as the Yukon, Northwest Territories and Nunavut. Remote regions may also be able to monitor entry points more easily than larger, better-connected centers. This policy choice meant that the tourism industry was disproportionately affected compared with many other Yukon businesses, and it will not be sustainable in the long-term under these conditions.

A further consideration for the Yukon, and other jurisdictions that did not experience high COVID-19 case counts earlier in the pandemic, was that moving forward with reopening plans meant increasing cases and therefore risk, compared with areas that reopened due to decreasing case counts. There was also a question of timing; reopening shortly before graduation, when there was increased travel between Yukon communities, likely contributed to the rapid outbreak spread.

A central insight, of importance in late 2021 as other Canadian jurisdictions reopened, is that high vaccination rates and mandatory masking were not enough to prevent outbreaks in unvaccinated populations, which put a strain on the local healthcare system. Secondary school students, as part of the 12–17 year age group, were not eligible for vaccination prior to reopeningFootnote 27, whereas children in daycare were too young to be vaccinated, and some communities had lower vaccination rates than othersFootnote 28. Policy decisions based on an overall percentage of vaccinated people ignore that unvaccinated groups, because of age or lifestyle, tend to interact, which facilitates disease spread.

Although children do not typically suffer severe illness from COVID-19Footnote 29, daycares were hotspots in Yukon’s summer outbreakFootnote 22. To manage the outbreak, the Chief Medical Officer of Health recommended that parents who are not essential workers keep their children home if possible. As parents are limited in their ability to work without access to reliable childcare and typically women bear more of the burden for childcare responsibilities, which has been exacerbated by the pandemicFootnote 30, this recommendation came with economic consequences that disproportionately impacted women. Currently, children younger than five years of age are ineligible for vaccination and are therefore vulnerable to the more contagious variants of COVID-19.


A lesson can be taken from the Yukon’s experience: travel restrictions in the remote region were effective at mitigating disease importation early during the pandemic, but once these restrictions were removed, the highly contagious Gamma variant circulated in unvaccinated populations. Even with high vaccine uptake and masking, outbreaks occurred that strained public health and healthcare capacity. This is a cautionary tale for other jurisdictions as public health measures are being removed and vaccine uptake has plateaued. Extended COVID-19 disease burden in the Yukon could include unintended consequences, such as more paediatric cases, daycare and school closures and their associated economic and mental health impacts, more difficulties for businesses, and an overburdened healthcare system. These impacts are also being seen elsewhere in Canada during the fourth wave. Widespread vaccination across age groups and communities is needed to reduce the severity of future COVID-19 waves.
