In my experience using a Netherlands based S6 Edge, I got the updates about a week or two after they were released in the Netherlands and got them over wifi. Maybe the carrier (vodafone) has cell partners in the US, but I ran it on AT&T. I suspect you will get the update in due time. Since they do rolling updates by geography, they'll probably first finish the Canadian clients, and then put the update out to clients outside of Canada.
