While it could just be overloaded due to how many fires there are, last year they changed how it displayed to make it look like they had better air quality than they did so it's not out of the realm of possibilities.
Man, wait till you read about the whole maple syrup industry conspiracy. They got entire reserves of syrup in Canada, and they have this regulatory board that controls the supply leaked out to drive prices up. There's a bunch of dubious grade marks handed out that determines the wealth of your syrup. And the maple syrup regulatory board is experimenting with suicide bomber kangaroos in Australia, which is weird they have a military branch for the maple syrup sector.
It's a whole rabbit hole.
Today there was an air quality warning here - in Tennessee - from the Canadian fires !!
