Growing up in Toronto during the 70s, I remember several expressions I've rarely, if ever, heard elsewhere.

"No guff"--meaning something like "no, really?" in a sarcastic sense

"My foot"--maybe something similar to "my ass!"

And later, when living in Montreal, I remember several expressions that were basically direct translations from the French

"Me, I..."--from the French "Moi, je..."

"In place of"--instead of "instead of"
