Doing float plane training in Canada

I'm a Canadian citizen, a permanent resident in the US with a US ASEL-IA.
I'd like to get a float plane rating, but the school that most appeals to
me is in Canada. They have information on their web site about getting a
Canadian Limited Term Private Pilot License in order to do the training
there, but say to "apply to your local Civil Avation Authority for
information to have the rating added to your foriegn pilot license."

Has anybody here done that? How hard is it?
