No, northern Canada is just really cold. The Gulf Stream makes a difference in Europe in general, not just the seaside. Eg, Lillehammer, Norway is around the same latitude as Whitehorse, Canada but the average December high/low is a balmy -3°/°-8 compared to -10°/-18°. And Bergen is at the same latitude as those places but is even warmer, with a climate similar to Vancouver! That always amazes me. As far as Hudson’s Bay being “seaside”, Churchill, Manitoba is on the southwest shore and is a great place to go and see polar bears. If climate change does end up affecting the Gulf Stream, northern Europe is in for a tremendous cold shock.
