Last night saw Donald Trump win the American presidential election over Hillary Clinton.

The campaign caught the world's attention, and among those was Brandon University Political Science Professor Kelly Saunders.

She sums up her reaction as shock and disbelief, adding the result may be an indication of the level of anger among the American people.

"They're worried about their economy, they're worried about terrorism, they're mad at Washington for not delivering, I think, on the American dream. Yes, the economy is beginning to rebound, but the kinds of jobs and the kinds of incomes that might have been there 10, 20, 30 years ago aren't there anymore, and people are angry about it, and they're looking for a place to launch that anger."

Saunders thinks Canada's economy could suffer if Trump moves forward on re-negotiating agreements like NAFTA.

"And that's going to be very bad, I think, for a lot of our exports. Just our trading relationship in general is going to really enter a whole new era that's going to be difficult for Canada. Of course, the United States is our largest trading partner, we rely on access to the market for goods. Certainly, our agriculture sector relies on our relationship, and that is going to be troubling for us specifically in Manitoba."

She adds this may be troubling for the federal government, and Prime Minister Justin Trudeau.

"It's not that there wouldn't be challenges ahead with a Clinton administration, in terms of protectionism. But the Trump scenario is not what we had hoped for in terms of not only our trade relationship, but our security relationship as well. Donald Trump has also indicated that he wants to pull the United States out of NATO, which of course, we rely on in terms of our security interests. There are a number of really important policy files that now could be detrimentally impacted."
