I grew up in Ontario, never heard "ou" as "oo" there.
My family has lived in New Brunswick (an Atlantic province) for years, never heard it there either.

The Canadian "ou" is distinctive, but to a Canadian ear that only distinguishes it more from "oo"

I think this has more to do with the American ear than the Canadian accent.
