Eastern Canada, perhaps? Because B.C. wildfires have made Washington maps go to "very unhealthy" (AQI 201-300), so I'm sure B.C. was above that.

(I'm not sure what "yellow" means where you're at. It's "healthy" according to https://www.airnow.gov/aqi/aqi-basics/).

In BC when they were at their worst the sky was dark yellow and the sun was a very dark blood red. It was like something I’d never seen before. Think the light level in Seattle during an extremely overcast day with a low ceiling, but everything you look at has been coloured yellow by the sunlight passing through the smoke. It looks a lot like photos from the various Mars missions.

That kind of international cooperation between the US and other countries is something we just don’t see anymore.

Also competition at the same time.

Canada normally surpasses the per-capita carbon emissions of the US. Now, they’re setting records ablaze and further cementing their lead.
