After visiting several spots in Montreal I came to two conclusions... No quality roasters in Montreal (someone should get on that). Not many people serve Canadian roasted beans... I found Phil and Sebastian and of course 49th and parallel, which I found would have been fine if executed correctly.
With all that being said I think that Cafe Plume serving Verve out of Santa Clara was by far the best execution for a simple 6-8oz Americano. Perfectly done and Verve is mighty tasty! I don't think they do pour overs here though so if thats what you are looking for you are better off trying Myriade (Serving 49th, and Heart when i was there).
