The process at the Montreal Consulate was pretty straight forward. You line up on the street outside (at the side door - not at the front of the building) and wait to go in. Once inside it is a typical federal building. Metal detector etc... Do not bring any extra stuff with you. Even a purse or briefcase as you will not be allowed to bring it in. You can bring in a file folder for your papers. Wait time wasn't too long and the interview was very basic and straightforward. I was given an approval letter on the spot. Everyone was nice enough, although not overly excited about their jobs I don't think. Kind of a boring process for everyone involved I think.
