The Canadian smoke gives the light a lovely autumnal feel. I don't know that it can be captured on film - Kodachrome 25, maybe.
An 8x10 B&W contact print might catch the quality of the light, but I wouldn't put much stock in it.
"With 4x5 you can see all the details, with 8x10 you can see the air." No idea who said it, or even if anyone said it.
'Course, you get enough smoke and it all turns to Blade Runner. Wonder, if in the future, those movie scenes will be referred to as 'Canadian smoke sky.'
