It looks like there are at least some people in Canada who support the idea of opening up the NAFTA for re-negotiation:
The NDP is joining U.S. Democratic presidential hopefuls in their promise to change NAFTA, with Leader Jack Layton telling an American audience today the trade agreement needs to better protect workers and the environment.
In an interview, Mr. Layton said the New Democratic Party wants to join forces with the likes of U.S. Senators Hillary Clinton and Barack Obama, who are pledging to change the North American free-trade agreement in the Democratic nomination race.
"There are many Canadians who agree. Certainly the Democratic Party has long advocated that the environmental and labour standards in NAFTA be improved," Mr. Layton said.
