start here to establish that the RV is importable.
http://www.tc.gc.ca/motorvehiclesafety/safevehicles/importation/usa/vafus/list2/Section5_1.htm/Then do a search here and you will get the hoops. The primary issue is a letter/document from the manufacturer that certifies the RV has had ALL recall issues addressed and rectified. If purchasing from a dealer they will likely get this done and will likely have knowledge regarding the import process. However, best be knowledgeable, trust but verify. If private sale, getting the cert from the manufacturer in on you. This is the place to start as the import is going nowhere unless the import capability is verified and the recall cert is in place. There are also some rules about the import document(s) preceding you at the port of entry by three days. GST or HST is payable at the border.
RIVA and CSA certs are a real issue also.
As you have done it once, this time will go well.
Sorting out the licensing/registration issue is a Catch 22. Is the US temporary license valid in Canada? If not, how do you get the license in Canada? Not likely a license source at the border crossing! I doubt that any dealer etc. in Canada is likely to give you a temporary license.
