Last night was bad (far east side of toronto… like Durham Region). It was over 180 and not only could I smell the smoke from inside the house, but my eyes were burning, too.
Having flashbacks to the fires from a couple of years ago. We were nowhere near (these were the Quebec fires IIRC) but outdoor AQI was bad for weeks, regularly topping 300 and peaking at 4-500. Had everything closed up, AC and multiple HEPA purifiers running, and it was still awful indoors.
Resource hidden where we can’t see it? Best to assume it’s infinite and there will be no repercussions.
