I have a friend from Toronto that worked the bar last January to March. We didn't stay there but did enjoy the hotel bar great staff. The owners are a stich. It is not exclusively gay but does cater to the gay community. The people we met that stayed there that were not gay seemed very comfortable. I personally have never found straight people to be uncomfortable around me. By and large most of our friends are straihgt and married. There is a new gay bar open in town I here is the bomb. Even better than Michael's 69. I think the name is Bloo I guess it is very trendy and cheek. I get the impression the kind of style like Deseo. Might be worth a look see.
Side note. Its been a while since I've been to Montreal went to school for a while at Laval in Quebec Cite. Loved Quebec!
