Canada has no ADS-B mandate, so you don't need ADS-B in any format up there at all. They also have no Mode-S mandate, so Mode-C is fine. However, since you DO need ADS-B out in the USA by 2020, it's generally cheaper to buy a Mode-S transponder for ADS-B Out than it is to buy a UAT AND a Mode-C transponder.

Transponder Requirements
The U.S. Government requires aircraft to be equipped with a Mode A and Mode C transponder to cross the U.S. border in either direction (inbound or outbound). If you do not have a transponder, you must contact the U.S. Transportation Security Agency (TSA) for a waiver.
Aircraft are to be equipped with a Mode C transponder when operating in Canadian Class A, B, C, D and E airspace, as specified in the DAH (TP 1820E), which is available from NAV CANADA (CAR 601.03).
