Stephen Harper says the U.S. faces a "significant threat" of retaliation over the Buy American clause from Canadian provinces and cities that intend on shutting U.S. companies out of bidding on Canadian infrastructure projects.
Via the National Post:
"Quite frankly the biggest risk we have to global economic recovery is an increase in protectionism," Mr. Harper told Fox host Neil Cavuto in a wide-ranging discussion on the economy and Canada-U.S. bilateral issues."
"The worst possible signal that we could send to the world right now would be an increase in protection and particularly a procurement trade war between Canada and the United States."
Canada is by far the US's largest trading partner and all around best friend.
