More Canadians are being treated for COVID-19 in intensive-care units than at any time in the pandemic, a situation that underscores the threat of the highly contagious variants that contributed to Ontario’s decision on Monday to close schools indefinitely.
The rising rate of new coronavirus infections in Canada is putting extraordinary pressure on hospitals, particularly in the Greater Toronto Area, the epicentre of the third wave. There is also a record number of COVID-19 patients in intensive-care units in British Columbia.
Although the total number of people fighting COVID-19 in hospitals across the country has not yet eclipsed the peak of the second wave, the number requiring critical care has. At least 1,040 Canadians with COVID-19 were in intensive-care units as of Monday, nearly twice the number at the beginning of March and about 150 more than at the height of the second wave, according to The Globe and Mail’s tally of provincial data.
Canada reported 8,536 new infections on Monday, down slightly from a record high of 9,254 on Friday. The seven-day average of new cases a day – a measure that smooths out day-to-day blips in the data – reached 8,091, nearing the previous peak of 8,217 on Jan. 10.
One hopeful note in the otherwise grim statistics is the national COVID-19 death count, which remains low compared with previous waves – a testament to the effectiveness of immunization for vulnerable Canadians, including residents of seniors’ facilities. The country is currently logging 34 COVID-19 deaths a day, on average, compared with peak seven-day averages of 177 deaths a day in the first wave and 162 in the second.
However, deaths are a lagging indicator, and the full story of Canada’s third wave has yet to be written.
The Atlantic region continues to be a beacon of COVID-19 control, with no new cases reported Monday in Newfoundland and Labrador, a province that recently beat back an outbreak caused by the B.1.1.7 variant first identified in Britain.
The B.1.1.7 variant is the driving force in the spike in Ontario, where daily case counts topped 4,000 for three of the past four days, and where 619 COVID-19 patients were in the ICU as of Monday.
Ontario Premier Doug Ford announced Monday that all students in the province would return to virtual learning when April break ends in a week. He gave no date for when students might return to their classrooms.
Local medical officers of health in Guelph, Peel Region and Toronto had already closed schools before the break.
On Monday, Toronto Medical Officer of Health Eileen de Villa briefed the city’s board of health and released new modelling showing Toronto on course for approximately 2,500 daily cases if transmission rates remain unchanged. The city reported 1,296 new cases on Monday.
The city later confirmed that 20 per cent of Torontonians have now received a first dose of vaccine.
Toronto’s latest available data show that the city’s racialized and lower income residents continue to bear a disproportionate weight of COVID-19 infections and hospitalizations.
Based on data collected through the end of February, 76 per cent of Toronto’s COVID-19 cases have been among its racialized residents, even as they make up only about half of Toronto’s population. Poorer Torontonians who caught COVID-19 have also fared badly. Those deemed lower income were three times as likely to be admitted to hospital than those who are not, after adjusting for age.
In B.C., the province reported a record 121 patients in critical care as of Monday. The total number of COVID-19 patients in B.C. hospitals – 368 – is not a record, but it is close, B.C. Health Minister Adrian Dix said.
However, he said that, “hospital occupancy across the system is manageable,” even though Vancouver General, Lions Gate Hospital and Surrey Memorial are nearing 100-per-cent capacity.
Saskatchewan is now just below the peak of ICU patients it reached last week, while in Quebec, Manitoba and Alberta, the number of COVID-19 patients requiring critical care in the third wave is so far well below the peak of the second.
Cases began rising in Quebec two weeks ago, reaching about 1,500 a day in the past week, driven by major outbreaks in Gatineau, Quebec City and nearby regions. Montreal, the city that has been a constant national hot spot, has had a slower rise. Hospitalizations have risen 23 per cent in a week in the province and ICUs are at just less than half their COVID-19 capacity.
In Alberta, front-line doctors are starting to see the effects of the third wave.
Neeja Bakshi, an internal medicine specialist, worked on a COVID-19 ward in Edmonton over the weekend. The team admitted four or five patients over 24 hours, she said, compared with one or two in the same time period a week ago. Patients averaged around the age of 50, she said, making them younger than those admitted to hospital in the first and second waves.
“I think the ICU is going to get overrun because these are all young patients so we want to give them absolutely everything we possibly can to try to reverse it,” Dr. Bakshi said.
Her Edmonton hospital does not feel as chaotic as it did in December, but admissions are rising and the variant strains put pressure on the system in the way the original did not. In Alberta, patients infected with the P.1 or B.1.351 variants first identified in Brazil and South Africa, respectively, must be isolated from others with COVID-19. Patients with B.1.1.7 are permitted to share a hospital room with patients infected by the original variety.
“Capacity is a problem and it is going to be a bigger problem this time around,” Dr. Bakshi said.
Alberta counted 390 COVID-19 patients in hospital as of April 11, filling 86 per cent of the beds available to people infected with the virus. Of those in hospital, 90 are in intensive care, up from 76 patients a week prior. Alberta’s ICU occupancy peaked during the second wave on Dec. 28, 2020, with 151 patients.
