Why are all prices so high in Canada?

Why is it that even after currency conversion, Canadians have to pay about 30% more for absolutely every consumer product around? For example, if you get on Best Buy’s Canadian website, and convert the prices to US dollars, than look at Best Buy’s US website… you’ll see that Canadians have to pay like 25%-30% more for EVERYTHING!! WTF?? Then throw in our taxes, and we’re actually paying about 35% more for everything.
