Wow, nice find of that map that shows the extensive spread of the wildfire smoke. You can really see the darker shades being near the site of the burns in Canada, and surprising so much of that smoke has ended up in the United States too. Of course, there are also wildfires in the U.S, but I'm not sure if its as much as Canada has currently.
I hope you stay safe out there, especially from those dangerous fires!
It's ironic how a century or so of purposefully trying to fight and eliminate wildfires have actually caused them to overall become worse, as they burn much brighter and hotter than back in the day. The wildfires are actually part of a forest's natural cycle, where it clears out crowded or dead debris and foliage on the ground to allow for new growth to come in. Since we constantly put them out, lots of dry, flammable material is left for fires to use as fuel if one is happened to be sparked. Obviously homes, infrastructures, and whatnot need to be protected, but now we are working so much harder to put out wildfires because of it. Controlled/prescribed burns are great ways to lessen the severity of wildfires and even prevent them by clearing the dense foliage on the ground that was supposed to be done naturally. It also releases nutrients into the soil further helping the aid of growth. Some pinecone trees also need that heat from the fires to open their cones and disperse seeds on the ground. If you're interested about this topic, go search for it on Wikipedia. It's also interesting to know that according to Wikipedia, the indigenous people in North America and Australia have done prescribed burns, so it has been done way before us.
