Summer 2017 I purchased a 2013 Escape
15B in USA and imported it back into Canada. Process was mainly painless, except to my wallet. You need to pay GST on your purchase at the border and then you have to go through the RIV program before you can register it in your province. This involved a fee of about $300 and a visit to a registered inspection company (in my case Canadian Tire) to have the trailer inspected. Once it passes the RIV process, they give you a form that allows you to register the trailer. There is no provincial sales tax here in Alberta, so I did not pay any provincial tax, but you may have to pay provincial tax on the trailer when you register it in another province.
