WE have Verizon Unlimited and Canada is included and just got back from 2 months in BC, Yukon and Alaska. We found service spotty (understandable) in BC and the Yukon. In proximity to major cities and towns it worked pretty well. In AK, it worked only in towns (Tok, Valdez) until we got close to Anchorage when service became pretty consistant. There looked like cell towers in places where we had no service so I think there is something out there better but would not know what it would be and was pretty happy with what we had.
BTW, our Hotspot also worked where our phones did.
