COVID-19 in Ontario is now primarily a Toronto-area problem, figures show |

Toronto and its surrounding regions account for a disproportionately high number of Ontario's new cases of COVID-19, according to a CBC News analysis of provincial data on novel coronavirus infections.  

More than three-quarters of the active cases of COVID-19 currently listed in the province's database are found in the five public health units of Toronto, Peel, York, Durham and

Halton regions, an area that accounts for less than half of the province's population.

This is a clear shift from the first month of the pandemic, when cases were more evenly distributed around the province, and that shift is prompting some experts to recommend that the province relax the lockdown in some regions, while clamping down in areas where cases are rising.

In early April, when Ontario hit 5,000 confirmed cases of COVID-19, Toronto and the GTA accounted for 52 per cent, according to the province's daily epidemiology reports. However, Toronto and the GTA account for 76 per cent of the roughly 6,600 infections that have happened in May.     

The new data lend further heft to arguments that the provincial government needs to consider a regional approach to the fight against COVID-19 in Ontario, something that Premier Doug Ford has resisted until now. 

"To treat the province as one unit doesn't make a lot of sense," said Dr. Michael Warner, medical director of critical care at Michael Garron Hospital in Toronto.

"The number of COVID-positive cases is increasing, but I think the more important question is within the province of Ontario, where are those cases actually located?" Warner said in an interview on CBC Radio's The Current. 

Ontario's total daily number of new cases headed on an upward trend from May 10. A closer look at the data shows a disproportionate share of those new cases is found in the five GTA public health units. 

Of the 3,931 infections that have happened in Ontario since May 10, the GTA's public health units account for 3,054, or roughly 78 per cent. 

The growth in new cases in Ontario since early May "is primarily a Toronto problem," said Dr. Alon Vaisman, infectious disease physician at the University Health Network. 

"Other parts of southern Ontario and especially northern Ontario haven't seen rising numbers; mostly it's been a decline." 

Vaisman is urging provincial officials to look far more closely at the specifics of the data to craft the best pandemic response. 

"If you go more deeply and you see a rise of cases in a certain demographic, either old or young, or certain regions, or certain professions — then you could really just tailor your approach to that problem," Vaisman said in an interview with CBC News.

"If all you know is that it's a lot of cases in Toronto, it doesn't make much sense that in Kingston they should be shutting down parks."   

The province's database on Tuesday showed 4,110 infections as "not resolved," meaning that the person is still considered infectious. The GTA's public health units account for 3,171 of those active cases, or roughly 77 per cent. 

Outside the Greater Toronto area, only a few urban areas continue to see a significant number of new cases. The Ottawa, Hamilton and Windsor-Essex public health units together with the GTA account for roughly 90 per cent of the province's new infections since May 10. 

That's why a range of experts are suggesting Ontario's public health leadership focus its response more tightly on hotspots, and consider allowing parts of the province that are largely unaffected to resume their economic activity more quickly. 

That's the kind of approach being taken by premiers François Legault in Quebec and Jason Kenney of Alberta. They are keeping restrictions in place longer in the hardest hit parts of their provinces. In Quebec, that's the Montreal area, while in Alberta, the cities of Calgary and Brooks. 

"Ontario is very diverse, so it doesn't make sense to have a policy that applies to the entire province if the entire province is not being affected," said Dr. Jeff Kwong, an epidemiologist at the University of Toronto's Dalla Lana School of Public Health. 

"The policies that you bring into place in areas like the GTA could be different from, let's say, Sault Ste. Marie or Sudbury," Kwong said in an interview with CBC News.   

"Maybe we don't need to apply the same degree of lockdown, or we could be in different stages of reopening, between Toronto and other regions," said Dr. Lauren Lapointe-Shaw, an epidemiologist with the University Health Network.

But that's not the approach favoured by Ontario's chief medical officer of health, Dr. David Williams. 

"Let's say hairstyling in one [pubic health unit] is open and the others not. So then everybody in this one just drives over, gets their hairstyle in that one, and so you bring all those infections over there," Williams said Tuesday during his daily news briefing.  

Despite acknowledging the existence of COVID-19 "hotspots" in parts of the province, Ford has rejected anything other than a pan-Ontario formula for imposing and easing the province's semi-lockdown. 

Some urban areas of Ontario are "lighting up like a Christmas tree," Ford said Monday during his daily COVID-19 briefing. . 

"We're going to get people out where the hotspots are and get them tested," he added but did not elaborate on the plan.
