When the French lost to the british in 177x-ish, people of Quebec were left to fend for themselves. They fought tooth and nail to preserve their culture and language and I think to this day there's still this inertia going on in the way modern French Canadians think.
Moreover, there has been a study/survey showing that isolated culturally homogeneous communities tend to heavy-handedly police (the US style) the use of their native languages. I wish I could find a link to that study :-(
As a native russian speaker living in the US i can actually confirm that the study seems to ring true; i dislike (very much so) when russian speakers start mixing in english words.
But on the other hand, your Québec friend will tell you that you can "plugger" your "laptop", he has "checké" that there is a "plug" that is "loose" on the nearby "powerstrip".
I lived there for a bit more than a year, and I'm pretty sure they use at least as many anglicisms in daily life as we do in France. However, we both pay more attention to the anglicisms used by the others when we're in their country because we're not used to them.
They avoid them a lot more than we do in written language though.
Lol, I always felt jealous of them. They would just blend in with the crowd. In contrast, I have a very pronounced accent in English and don't even get me started on my French.
