Klinton,
But Canada stands to lose much more over the long term if they close the border to imports, including the chains like WalMart!!
I am sure the initial boost to the economy (providing work via construction, jobs, etc.) was greatly beneficial to Canadians!!
As far as the closing of smaller stores, are there any other avenues for the small business owner to avail themselves to? Here in the U.S. there are government subsidies and organizations such as the Small Business Bureau, that can in most cases at least help steer those businesses in the right direction until the economy straightens itself out!!
