Escape will send you documentation that allows you to register the trailer at any Alberta registries. There is no need for the trailer to be physically present. For us it was a simple matter to register and insure the trailer before our trip to Chilliwack to pick it up. The Alberta registration is perpetual and does not ever need to be renewed as long as you own the trailer.
