Yes, there's like 2K cases in Monteal. Toronto has a bigger population though and they have subways as well. So does Vancouver, but at least ours are mostly above ground and get some fresh air at least.
I read a while back when the border closing talks began that a lot of snow birds came back to Montreal. They were parked in the Walmart parking lot with their RV's and then hoarded supplies and went home.
They could've brought it with them.
