J'ai trouvé un petit video qui explique pourquoi les Français et les Québecois sont aujourd'hui ''excités'' quand ils n'étaient pas auparavant.
The ngram search in English shows usage going up somewhere in the 70's/80's, but I'm pretty sure this song from 1982 had something to do with it:
His ngram search is for international French, and Quebecers barely register close to 10% of French world population, so our usage would barely show-up.
The video doesn't really deal with the earlier use by Quebecers which probably register closer to the US.
I would need to ask older family members if they remember when it started getting used here. Personally, I grew-up in the 80's and as far as I can remember, it was used in my youth by family members who barely spoke English, but I might be mistaken.
There's also no way to know if our usage influenced France towards it or if it was simply the same american influences. I would bet on the latter.
