Miss Canada Sahar Biniaz -- Justin Bieber Is a Douche!

Turns out Justin Bieber is not loved by all Canadians -- in fact ... the hottest woman North of the Border, Miss Canada herself, thinks the Biebs is "a bit of a douche."

Sahar Biniaz, the reigning Miss Universe Canada, told our photog last night that she once tried to get a picture with Bieber ... but he blew her off!!!

Biniaz isn't even willing to let bygones be bygones ... saying she doesn't even want the pic anymore.
