TORONTO (AP) — Former U.S. Secretary of State Hillary Rodham Clinton said Monday that the proposed Keystone XL pipeline shouldn’t be seen as a proxy for the relationship between Canada and the United States.

Clinton gave a speech in Toronto to promote her new book before taking questions from Frank McKenna, Canada’s former ambassador to the U.S. McKenna said the Obama administration’s delayed decision on whether to approve the pipeline is source of tension and is increasingly viewed as a proxy for the relationship.
