When I went to Montreal for their autoshow this January, the most common brand on the road was Pontiac. Runner up was Toyota.
Almost every second or third car on the road was a Sunfire or Grand Am.
Pontiac is HUGE in Canada.
Well, dealers here are ussually grouped. You have Chevrolet as a standalone (used to be Chev/Olds). Then there is Pontiac/Buick/GMC. And you might have Saturn/Saab/Hummer (used to be Saturn/Saab/Isusu). In some cases, Cadillac (mainly standalone) is grouped with Pontiac and Buick.
I noticed one dealership in Milton (north of Toronto) is replacing Pontiac with Chevrolet.
They sell Pontiac/Cadillac/Buick/GMC.
