The U.S. election is shaping up to be an “unpopularity contest as opposed to a popularity contest” and some are expecting as many as a million Americans will depart for Canada if Donald Trump is elected, Canada’s former ambassador to the United States told BNN.

“This is certainly the most unusual and unconventional American election that I’ve seen in my lifetime,” Derek Burney said, a day after Trump secured the 2016 Republican presidential nomination in Cleveland.

Burney added that most Americans are “perplexed” about choosing between Trump and presumptive Democratic nominee Hillary Clinton when the election takes place Nov. 1. “I don’t find a whole lot of enthusiasm for either candidate,” he said.

No matter who emerges as U.S. president, neither a Trump nor a Clinton administration would provide many advantages for Canada, Burney said.

Trump, for example, has called the North American Free Trade Agreement a “disaster” and said that he would want to renegotiate the deal between Canada, Mexico and the U.S. that stretches back to 1994. Meanwhile, Clinton has “flip-flopped on a number of issues that directly impact Canadian interests,” Burney said, noting her switch from favouring to opposing the Keystone XL pipeline and the Trans-Pacific Partnership.

“She’s been pulled left by Bernie Sanders and the campaign, so it’s difficult to know where she’ll end up,” Burney said.

On the other hand, Trump and the Republican platform’s call for a revival of Keystone XL would be a positive for Canadian interests, according to Burney.

“That would be a great boon not just for Alberta but for Canada as a whole,” he said.
