Zero Canadians pronounce words like that. We do pronounce “ou” differently than Americans, but we don’t say “oo”. More like “ow” for Canucks, and “ayw” for Yanks.

I’m Canadian and used to think we didn’t actually have much of that exaggerated ‘Canadian twang’ people say we have, but having lived in the UK for the last 16 years and just returned from a 6 week visit, I’m saddened to admit that I was very wrong. 

Not everyone has it, but most do in varying degrees.
