You will need to take the TT to Canadian Tire (of all places) to complete the process as a final step when it is time to import into Canada. They will complete the application with axle ratings.
We purchased our TT new from a Ohio dealer and imported it into Canada. The process was simple and cost just over $200 excluding GST at the border.
As for the TT being Canadian compliant, the VIN sticker from Keystone on our TT states that it meets the Canadian Motor Vehicle Safety Regulations and that is the standard sticker. So I am not sure what you may have paid extra for.
