Pierre Elliott Trudeau International Airport

Dorval Aviation, a flight school located on the field, can rent you a C172 to fly around the area following a short rental checkout with an instructor. A C172 floatplane is also available on the river northeast of Montreal.

Montreal's a great city for food, but don't bother with the airport -- there's not much there, especially once you're through security. Bring something with you.

They make you go out into the public area and then line up for security again when transferring from an international to a domestic flight -- it can be pretty frustrating when the security lineup is long and you have a tight connection.

Unfortunately, CYUL has brought in landing fees for private planes as of 2007. I think it's around $40 or so even for a light single (!!!).
