I don't think a Brit moving to Quebec will be in that much of a cultural shock. Lots of old buildings, old traditions etc in both places.

I grew up in Montreal (a bit different than Quebec city but akin) and I have traveled extensively in the UK. I've never found the UK to be particularly difficult to travel in.

Generally speaking, Brits (and other foreigners) are better accepted than English-Canadians from, say, Toronto. (yes I'm putting my asbestos underwear on for that one )
