So, another American retailer decided to set up shop in Canada. This time it is Nordstrom. Despite the fact that Canada's population is only about 10 per cent of the USA's, it seems to be an attractive proposition for American retailers to do business here in Canada. Sure, our economy seems to be in better shape than theirs, but even long before the North American economies soured, the Americans had a good retail presence in our country. So, why is it that they keep moving in?
