Sometimes people are reluctant to say where crews stay- for their sake....
But since it's closed (to become McGill dorms

) the Renaissance Montreal used to have a _lot_ of crews- kinda surprising, as it was a bit East and North of the "downtown" hotels, so farther away from YUL.
A woman at check-in once gave me one of the chocolates given to her by a crew by the then newly-launched Swiss :-) and there's were plenty of other crews there, as well.
