As others have said- buying a glider out of Canada is not difficult since 99% of all gliders in Canada fly under a standard C of A, unlike all the experimental gliders in the US.

This means that Canadian gliders have not been modified and still conform to the original type certificate and for the most part repairs were properly performed and documented by a certified shop. Of course, this is something that you will have to assess with each glider.

It is much easier buying out of Canada than importing to Canada!
