The gotcha in buying a glider from Canada is that some state DMVs can be finicky with trailer imports - same applies to Canada with the addition of a detestable, obtuse and lethargically responsive federal agency called the Registrar of Imported Vehicles.

Many gliders in Canada were imported from the US; so, if the original US records have been preserved, your local FSDO shouldn't make any problems. Do check with them first.

Much easier, cheaper and quicker to get an imported glider flying in the US than in Canada.

With the Canadian dollar down, it's a good time to buy in Canada.
