"A little-known clause in NAFTA states that even in the event of a severe energy shortage, Canada cannot cut off its oil and gas exports to the United States--we can only reduce the flow south by the same rate as we reduce our own domestic consumption."
Wow. I guess when we account for 40% of Canada's GDP, we can really ask for anything we want. Why else would anyone agree to THAT agreement?
