Silver jewelry wholesale sources in Canada

I was told by another retailer recently that jewelry can be bought
at a significant discount in Canada due to advantages due to
differences U.S.-Canadian exchange rates; do any of you have any
personal experience with buying fashion/silver jewelry in Canada, and
if so, is this info. accurate?

Secondly, I’ll be traveling to Vancouver in a few weeks; is there
any kind of wholesale scene/area there I should be aware of?

Thanks for any advise or responses!
