Whenever I'm in Montreal I always stop by Off the Hook on St Catherine's. Staff is friendly. Store isn't that big but has a good layout. Solid men's hypebeast store - with brands such as Stussy, Brixton, Patagonia, Carhartt, herchel bags, the Hundreds, Nike Tech. The sneaker collection is okay - I've never found anything good. Lots of runners. There is a sale section in the back of the store. Also there is a Vans section on the 3rd floor but I've never been.
