President Obama visited Canada on Thursday in his first trip abroad since taking office. Obama spent seven hours in the Canadian capital of Ottawa meeting Prime Minister Stephen Harper. Obama called for a new round of talks on adding labor and environmental provisions to the North American Free Trade Agreement.

President Obama: “With a NAFTA agreement that has labor provisions and environmental provisions as side agreements, it strikes me, if those side agreements mean anything, then they might as well be incorporated into the main body of the agreements so that they can be effectively enforced. And I think it is important, whether we’re talking about our relationships with Canada or our relationships with Mexico, that all countries concerned are thinking about how workers are being treated.”

Obama and Harper announced one initiative: a dialogue on developing clean energy. On the issue of Canada’s environmentally destructive extraction of oil from the Alberta tar sands, Obama was ambiguous. The President stressed the need to curb global warming but also noted Canada’s status as the top energy provider to the United States. On Afghanistan, Obama said he did not press Harper to reconsider Canada’s plan to withdraw its troops by 2011.
