EXCLUSIVETurns 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.
Watch the clip ... Biniaz cracks a short joke at JB's expense. Little guy can't catch a break these days.
