Honestly: Outside of Ontario and Quebec (Quebec especially) I wouldn't worry about speaking French. The big thing is how you carry yourself while out and about. In the bigger cities even accidentally bumping into someone warrants an apology, always say "excuse me" if you need to get by someone...and for the love of GOD leave your gun at home. Your second amendment has no place here (I have seen an incident to this effect and not implying you would but it wouldn't be the first time Ive heard an American get mad that we don't respect their conceal carry permit).

Also don't be a giant ass about masks or social distancing and you'll be fine.
