I have driven and flown into Canada with ham gear many time in recent years. Canada Customs should not have any problem with your radio equipment. Make sure you have your US ham license when traveling up there, and sign "mobile (or portable)" followed by the appropriate Canadian prefix for your location.
Industry Canada, the licensing authority in Canada, has a document that is the rough equivalent of FCC Part 97 called RBR-4 (Standards for the Operation of Radio Stations in the Amateur Radio Service). You can see this document at:http://www.ic.gc.ca/eic/site/smt-gst.nsf/vwapj/rbr4e.pdf/
Good luck and 73!
