Ontario reported 1,824 more cases of COVID-19 on Thursday and reached a key threshold when it comes to the number of patients in intensive care earlier than expected.As of Thursday, 203 patients with the illness are currently being treated in intensive care, according to a report by Critical Care Services Ontario. The number of patients in intensive care is notable because public health officials have said that 150 is the threshold for when unrelated schedules and procedures may be postponed or cancelled to accommodate the influx of COVID-19 patients. Models detailed by health officials on Nov. 26 forecasted that the number of COVID-19 patients in ICUs would not break 200 before next week, putting the province five days ahead of those projected scenarios."It is concerning that we are ahead of schedule," said Dr. Michael Warner, medical director of critical care at Michael Garron Hospital in the east end of Toronto. While some hospitals throughout Ontario have been largely unaffected by the second wave of COVID-19, those in hotspots are under increasing pressure, he added. According to Warner, 18 per cent of all ICU patients in Toronto hospitals have COVID-19. That figure rises to 24 per cent in both York and Halton regions.Furthermore, the Grand River Hospital in Waterloo Region paused elective surgeries this week after its intensive care unit reached capacity. And in Windsor-Essex, the Windsor Regional Hospital said high patient numbers were challenging the entire regional health-care system and had made it necessary to impose strict visitor restrictions in an effort to reduce transmission of the virus.Total admissions to intensive care during the first wave of the illness in the spring topped out at 270, Warner said, but hospitals were able to better cope because non-COVID-19 related procedures and care were cancelled.This time, he explained, that is not an option."There would be too much collateral damage," Warner told CBC Toronto. Similarly, the Ontario Hospital Association has urged the public to continue following public health guidelines in an effort to address capacity issues."Ontario hospitals are finding it increasingly difficult to maintain access to vital surgeries and procedures with COVID-19 cases rising," the organization said in a statement posted on social media."Hospitals are doing everything they can, but they need your support. Help stop the spread by making better practical choices every day."At the province's daily press conference Thursday, Health Minister Christine Elliott said the number is a concern, and noted some hospitals have had to put procedures on hold.She said the province has increased the number of ICU beds in the province, but health experts have routinely said that staffing needs to increase in concert with that number.The province is also looking at a "regional approach to surgeries," Elliott said, which would essentially mean that surgeries be moved to hospitals that have capacity for them."We want to keep those surgeries and procedures ongoing," she said.592 new cases in Peel Region, 396 in TorontoNew cases reported today include 592 in Peel Region, 396 in Toronto and 187 in York Region. The Middlesex-London public health unit also recorded 127 additional cases, though the provincial health ministry said that, due to a processing error, that figure includes three days worth of case data.Other public health units that saw double-digit increases were: * Waterloo Region: 87 * Halton Region: 68 * Windsor-Essex: 62 * Durham Region: 57 * Hamilton: 56 * Ottawa: 41 * Niagara Region: 25 * Wellington-Dufferin-Guelph: 23 * Eastern Ontario: 19 * Thunder Bay: 13 * Simcoe Muskoka: 11Also included in today's new cases are 122 that are school-related: 94 students and 28 staff members. Some 755 of Ontario's 4,828 publicly-funded schools, or about 15.6 per cent, currently have at least one case of COVID-19, while five schools are currently closed because of the illness.The additional infections push the seven-day average of new daily cases to a record high 1,769.(Note: All of the figures used for new cases in this story are found on the Ontario health ministry's COVID-19 dashboard or in its daily epidemiologic summary. The number of cases for any region may differ from what is reported by the local public health unit because local units report figures at different times.)Provincial Medical Officer of Health Dr. David Williams said Thursday that the seven-day average is now at 1,769 cases, with 87 per cent of those since Monday coming from red and lockdown areas of the province. Williams said the province plans to make an announcement about the movement of regions within its colour-coded framework Friday."The trends continue to go up at this time," he said, noting that there has also been a 20 per cent increase in hospitalizations since last week.Questions remain on vaccine rolloutPremier Doug Ford said Thursday the federal government has told the provinces that the first supply of vaccines will be approved and available in early 2021."Initial supply will be very limited," Ford said, adding that he still has many questions — specifically which vaccines will be coming to Ontario, how many, and when they will land."These are three fundamental questions that I've been asking for several weeks now. They remain unanswered," Ford said.Alberta Premier Jason Kenney, meanwhile, said Wednesday: "We've been assured by the federal government that shipments will begin to arrive by Jan. 4."Kenney said the province will have plans and its distribution network ready to go for when vaccines become available. Ford would not offer any details on Ontario's vaccination plan when pressed by reporters Thursday."What I can guarantee the people of Ontario is we will be ready," he said.Williams was also asked Thursday if the province would make vaccination mandatory."We can't force someone to take a vaccine. That's clear," he said. But what the province can do, he added, is make proof of a vaccine mandatory access to certain settings, such as long-term care facilities.Ontario's network of labs processed 52,873 test samples and reported a test positivity rate of 4.4 per cent. Another 58,320 tests were added to the queue to be completed. The province reported 14 further deaths of people with COVID-19, raising the official toll to 3,712.There are currently outbreaks in 116 long-term care homes on Ontario, including at Sunnycrest Nursing Home in Whitby, where 111 of the 136 residents and 30 staff members have tested positive.
