The COVID-19 pandemic in Canada is part of the ongoing worldwide pandemic of coronavirus disease 2019 (COVID-19). It is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Most cases over the course of the pandemic have been in Ontario, Quebec, British Columbia and Alberta. Confirmed cases have been reported in all of Canada's provinces and territories.[4][5]

The virus was confirmed to have reached Canada on January 25, 2020, after an individual who had returned to Toronto from Wuhan, Hubei, China, tested positive. The first case of community transmission in Canada was confirmed in British Columbia on March 5.[6] In March 2020, as cases of community transmission were confirmed, all of Canada's provinces and territories declared states of emergency. Provinces and territories implemented, to varying degrees, school and daycare closures, prohibitions on gatherings, closures of non-essential businesses and restrictions on entry. Canada severely restricted its border access, barring travelers from all countries with some exceptions. The federal Minister of Health invoked the Quarantine Act, introduced following the 2002–2004 SARS outbreak.[7] For the first time in its legislative history, the act was used, legally requiring all travelers (excluding essential workers) returning to the country to self-isolate for 14 days, until rules were changed to accommodate fully vaccinated travelers. Between July and November, the four Atlantic provinces

By mid to late summer of 2020, the country saw a steady decline in active cases until the beginning of late summer. In July, the four Atlantic provinces formed the Atlantic Bubble, which allowed unrestricted movement for provincial residents. Through autumn, there was a resurgence of cases in all provinces and territories.[8] On September 23, 2020, Prime Minister Trudeau declared that Canada was experiencing a "second wave" of the virus.[9] New restrictions from provincial governments were put in place once again as cases increased, including variations of regional lockdowns. In late November, the Atlantic Bubble was disbanded because of the second wave. The federal government passed legislation to approve further modified economic aid for businesses and individuals.[10]

Nation-wide cases, hospitalizations and deaths spiked during and after the Christmas and holiday season in December, 2020 and January, 2021. Alarmed by hospital capacity issues, fatalities and new cases, heavy restrictions (such as lockdowns and curfews) were put in place in affected areas (primarily Ontario, Quebec, and Alberta) and across the country. These lockdowns caused active cases to steadily decline, reaching a plateau in active cases in mid-February 2021. During a third wave of the virus, cases began rising across most provinces west of Atlantic Canada in mid-March,[11] prompting further lockdowns and restrictions in the most populous provinces of Ontario and Quebec.[11][12] Due to a relatively low volume of cases in the Atlantic provinces, the travel-restricted Atlantic Bubble was planned to reopen;[13] however, in late April, the third wave had spread to the Atlantic provinces. In response, Newfoundland and Labrador, Prince Edward Island, and Nova Scotia reinstated travel bans toward the rest of the country.

Following Health Canada's approval of the Pfizer–BioNTech COVID-19 vaccine, and later the mRNA-1273 vaccine developed by Moderna, mass vaccinations began nationwide on December 14, 2020.[14][15] On February 26, 2021, Health Canada approved the Oxford–AstraZeneca COVID-19 vaccine for use,[16] and on March 5, 2021, they additionally approved the Janssen COVID-19 vaccine for a total of four approved vaccines in the nation.[17] However, most provinces discontinued first doses of Oxford-AstraZeneca by May 12, 2021,[18] while the administration of the Janssen vaccine was determined unnecessary.[19] Canada became one of the most vaccinated countries in the world, with a continually high uptake of the vaccine.[20] Despite high general uptake of the vaccine, cases began to surge particularly amongst the unvaccinated population in provinces like Alberta, which had removed nearly all pandemic restrictions.[citation needed]

Near the end of summer 2021, cases surged across Canada, particularly in British Columbia, Alberta, Quebec and Ontario, described as a "pandemic of the unvaccinated". A July 2021 PHAC epidemiology report said that those who were unvaccinated represented almost 90% of COVID cases reported.[21] This fourth wave led to the reinstatement of pandemic restrictions like mask mandates in provinces such as British Columbia and Alberta.[22] Consequently, vaccine passports were introduced in all provinces and two territories.[23][24] Federally, Prime Minister Justin Trudeau implemented vaccination requirements for air travel, Via Rail and Rocky Mountaineer trains, and federally regulated workers, effective October 30, 2021..[25][26]

In January 2022, all of Canada's provinces and territories were experiencing record-level case numbers, primarily driven by the Omicron variant, which caused provincial and territorial governments to reintroduce restrictions surrounding travel and isolation. However, in mid-February active caseloads and hospitalizations began to decrease and towards the end of February 2022, almost all provinces and territories had announced plans to lift restrictions by early March or mid-March 2022, if epidemiology remained favorable.[27] By March 2022, more than 85% of Canadians aged five and over were fully vaccinated.[28]
