Time to leave NAFTA?

"I'm not looking for a trade war, nor am I seeking acrimony with my American friends. All I'd like is for my country, along with our Mexican partners, to admit that you can't do business with people who find it impossible to live up to the terms of a contract. And then quietly withdraw from NAFTA. But I do not think that it is unreasonable for the government of Canada to address the criminal trade practices of the United States, which it cannot do within NAFTA."
