Have you had a good north wind? I was in Snow Lake the last few nights visiting with your fellow Americans in the evening and it got Smokey a couple days ago, we had a good west wind. That smoke was from Saskatchewan border. It’s not too bad in Manitoba wildfire wise this summer.
Looks like Ontario has a good hot spot above you.
This map from NASA is super handy if you know how to select the different satellites & sensors. Not all the spots are fires if you look at the data.
