From Canada's National Post:
The federal government is looking to cut a deal with Washington that would persuade U.S. legislators to repeal controversial Buy American measures that Canadian firms say are costing them sales and forcing them to shed jobs.
The key element of such a pact, however, is getting the provinces and territories to open up their procurement markets to U.S. suppliers. At present, provinces and municipalities are not bound by global trade law and are free to discriminate against U.S. companies in favour of local suppliers.
So, in reaction to U.S. protectionism, Canada has responded by proposing additional trade liberalization? I'm not sure I like this lesson!
