The COVID-19 pandemic in Toronto is a viral pandemic of coronavirus disease 2019 (COVID-19), a novel infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), localized in Toronto. Toronto is the most populous city in Canada, and the fourth most populous city in North America.

On January 23, 2020, the first identified case of COVID-19 in Canada during the pandemic was admitted to Sunnybrook Health Sciences Centre in Toronto. The individual was first described as showing fever and respiratory symptoms, however this was later confirmed as a presumptive positive case of COVID-19 on January 25, 2020. On March 17, 2020, the government of Ontario declared its first state of emergency during the pandemic, followed by Toronto mayor John Tory declaring a local state of emergency March 23, 2020. Initial restrictions preventing essential businesses from operating (such as the closure of indoor dining and personal care services) continued through until June 24, 2020, when the government of Ontario allowed Toronto to enter Stage 2 of reopening. Toronto introduced mask requirements at all public indoor settings on July 7, 2020. On July 31, 2020, Toronto was admitted into Stage 3 of reopening.

During the summer of 2020, the city saw a significant decline of new cases, where the city had as low as 246 active cases at one point that August. Along with the province of Ontario and other areas of Canada, cases began to steadily rise in late summer and early autumn. Toronto, Peel Region, York Region and Ottawa began to face restrictions based on rising viral spread and were initially knocked back into a modified Stage 2 tier until the province introduced a new colour-coded Response Framework for the province involving five tiers based on regional COVID-19 numbers. In early October 2020, Toronto Public Health became so overwhelmed by new cases, it suspended extended contact tracing efforts. On November 23, 2020, Toronto was placed under lockdown, under which it remained until the province declared a province-wide shutdown beginning December 26, 2020. This included the declaration of a second state of emergency in January 2021 and stay-at-home orders for the entire province. Toronto remained under stay-at-home orders until March 8, 2021. On April 3, 2021, following an uptick in new cases in Ontario, (exacerbated by more aggressive variants of SARS-CoV-2) Toronto, along with the rest of the province entered a shutdown coupled with a stay-at-home order that lasted until June 2, 2021.

In December 2020, Health Canada approved the Pfizer–BioNTech COVID-19 vaccine and the mRNA-1273 vaccine developed by Moderna. Widespread plans for COVID-19 vaccinations across Canada and the province began during the week of December 14, 2020. On February 26, 2021, Health Canada approved the Oxford–AstraZeneca COVID-19 vaccine for use and on March 5, 2021, the Janssen COVID-19 vaccine was also approved. In conjunction with the Provincial rollout, the city has opened ten mass-vaccination sites across the city, with hospital and hospital-run vaccination sites, pop-up clinics, mobile clinics, pharmacies and family doctors participating in the administration of the approved vaccines.

On May 9, 2022, Mayor John Tory announced the termination of Toronto's COVID-19 state of emergency after being in effect for 777 consecutive days, the longest for any major city in the world.

Timeline

2020 January On January 23, the first presumptive case in Canada was admitted to Sunnybrook Health Sciences Centre in Toronto and placed into a negative pressure chamber. The patient, a male in his 50s who travelled between Wuhan and Guangzhou before returning to Toronto on January 22, contacted emergency services following rapid onset symptoms. The presumption of infection in the patient was made after a rapid test was done at Public Health Ontario's Toronto laboratory, and was announced on January 25. Final testing conducted at the National Microbiology Laboratory in Winnipeg, Manitoba confirmed the presumptive case on January 27. Authorities said that the patient was experiencing respiratory problems but was in stable condition. His condition later improved and he was released from hospital on January 31.

On January 27, the Chief Medical Officer of Health of Ontario announced the man's wife as the second presumptive case. Officials reported that she was in good condition and that she was asymptomatic.

February On February 24, Toronto's third and Ontario's fourth case of COVID-19 was confirmed after a woman tested positive following travel to Wuhan.

March

On March 5, more cases in Ontario continued to emerge, including a Toronto man who presented himself to Sunnybrook Hospital and tested positive following travel to Iran.

On March 12, 17 new cases were confirmed including a baby boy who had recently visited the North York General Hospital in the former city of North York. That day, the total number of cases in Ontario increased to 59.

From the initial case on January 23 to March 18, over half of the reported cases in the province of Ontario were reported in Toronto.

On March 13, York University, Toronto Metropolitan University (then known as Ryerson University), and the University of Toronto announced the cancellation of in-person lessons, with classes moved online.

April–May By May 4, 2020, outbreaks on four different inpatient units were declared at Toronto Western Hospital. The first was declared on April 18 while three others were declared on April 30. On May 10, another outbreak was declared on another floor at the hospital. While the term outbreak differs in definition by hospital, Toronto Western Hospital defines it as the confirmation of one positive patient per unit. On May 13, the hospital's emergency department declared an outbreak after five of its staff tested positive.

On Saturday, May 23, 2020, due to warmer weather, estimates of up to 10,000 mostly young people gathered in Trinity Bellwoods Park. Public outrage ensued as well as condemnation from Premier Ford and Toronto's medical officer of health Eileen de Villa. After making a tour of the city's parks and speaking with citizens, Mayor John Tory was criticized for lack of social distancing and improperly wearing a mask. He publicly apologized for his actions to following day. No social distancing fines were placed, however, there were several issued for public urination. Police presence was increased the following day to prevent any subsequent large gatherings. The following week, 'social distancing circles' were painted on the lawn in the park modelled after similar tactics used in San Francisco and New York City.

On May 27, the Province announced they would be taking over five long-term care homes following a scathing report by the Canadian Armed Forces citing neglect and abuse. Three of the five long-term care homes are in Toronto: Eatonville Care Centre, Hawthorne Place Care Centre and Altamont Care Community.

Despite social distancing policies, on May 30, estimates of up to 4,000 protesters gathered over the death of Regis Korchinski-Paquet, as well as congruent and concurrent protests in the United States and Canada following the murder of George Floyd. Protesters were encouraged to engage in social distancing and to wear face masks by Mayor Tory and Police Chief Mark Saunders. Early reports suggested most did wear face masks.

June On June 1, the city announced two phases for re-opening park washrooms with the first phase re-opening about 50 washroom sites by June 6 and the remaining by mid-June. The Toronto Police Service had issued several tickets at Trinity Bellwoods Park on May 23 after reports of public urination.

On June 5, the city told restaurants to begin preparing for reopening, with no date set, under strict guidelines. Dining room capacities would be reduced by 50 percent, tables cannot seat more than six people and staff will all be required to maintain a six-foot distance at all times from each other. The city released an extensive list of reopening guidelines. Premier Ford, Mayor Tory and Dr. de Villa suggest that outdoor patios will most likely see a reopening before indoor dining areas.

Again, despite social-distancing orders banning gatherings of more than five people (part of emergency orders by the province extended on June 2) thousands gathered in protests against racism on the weekend of June 5–7. Not Another Black Life, the organizers of the original protest one week before did not claim involvement and instead asked protesters who had participated in the original march to get tested for COVID-19 and self-isolate for two weeks.

In early June, the city announced the CafeTO program, aimed at expanding the patio area of restaurants and bars with patio licenses when allowed to reopen. On June 8, the province echoed these sentiments suggesting they would be eliminating 'bureaucratic red tape' to assist in these patio extensions.

On June 8, Premier Ford announced to beginning of rolling out initiation of Stage 2 of reopening. Gatherings of ten people or less are now allowed in the whole province. However the general Stage 2 approach would be done regionally and therefore Toronto and other areas in the GTA are excluded and will enter Stage 2 at a later date.

On June 9, city councillor Michael Ford (nephew of Ontario Premier Doug Ford) became the first city councillor to test positive for COVID-19. On June 11, 26-year-old Ford was briefly admitted to hospital.

On June 15, as another round of regions were allowed to move into Stage 2, Toronto, Peel and Windsor-Essex were still disallowed from moving forward.

On June 16, the Canadian Armed Forces, sent to help the troubled Eatonville Care Centre officially left the long-term care home. The home was declared 'COVID-19 free' by the home's executive director. The home saw at least 43 deaths, and 138 cases amongst residents and 106 cases amongst staff. All residents have recovered and all but one staff member have recovered.

By June 18, the city of Toronto had confirmed at least 1000 deaths related to COVID-19.

On June 19, the city announced that it will resume issuing marriage licenses from June 22 at the North York Civic Centre. The East York, Etobicoke, Scarborough, and York Civic Centres along with Metro Hall and Toronto City Hall service counters remain closed.

On June 22, the province allowed Toronto to move forward to Stage 2 of reopening, beginning 12:01 am on Wednesday, June 24.

At 12:01 am, some bars and restaurants opened Wednesday morning for a short time. On June 24, Mayor Tory announced ferry service will resume to the Toronto Islands on June 27, which had been closed to non-residents since the beginning of the pandemic. Riders of the ferries will be required to wear face coverings.

July

Beginning after Canada Day, street parking enforcement, as well as fare evasion enforcement, will return to Toronto and the Toronto Transit Commission respectively. Beginning July 2, face masks or face coverings will be required to be worn on the TTC.

Beginning July 7, face masks or face coverings will be required in enclosed, public places by law in the city of Toronto.

On July 29, the Ontario government announced Toronto was allowed to enter Stage 3 of reopening on July 31 at 12:01 am.

August On August 10, 2020, Toronto Public Health considered its four pandemic control indicators to be in the "green" for the first time. This analysis includes statuses on viral trends, access to personal protective equipment (PPE), laboratory testing and health system capacity.

September Amid back-to-school reopening plans debated at a provincial level, the Toronto District School Board decided to push back the start of school to September 15, 2020, and to have mandatory mask rules for students.
