Ontario Premier Kathleen Wynne said this morning that Donald Trump's victory in last night's U.S. presidential election came as a complete surprise.

"I was shocked, I'll be honest. I think it's very disappointing," she said during an interview on Metro Morning with host Matt Galloway. "I had not expected this outcome. I think that we all have to pay very close attention to how this happened and why it happened."

She said Trump, a businessman and Repubican populist with no political experience, was able to beat the more established Democratic candidate Hillary Clinton by tapping into voters' unhappiness with the current political system.

"People were voting against a system that they perceived wasn't working for them and was not fair," said Wynne.

Wynne has been critical of Trump, calling the Republican's campaign divisive, particularly on issues of race and equality.

"I'm not going to deny or try to pretend that there wasn't misogyny as part of this election campaign," she said. "But there was also racism, there was division on a number of levels."

Trump has vowed to tear up the North American Free Trade Agreement, which would have an immediate impact on Ontario.

"I'm very concerned for our trade relationship with the United States," she said. "We're going to have to see what is in his power to do."

"We're going to be fighting very hard here in Ontario to keep those open relationships. We are interdependent on the United States."

Many voters feel left behind, Wynne says

Galloway asked Wynne, who became Ontario's first female premier in 2013, if Clinton lost because she was poised to become the first-ever female president?

"I'm not in a position to say if that's the case or not," said Wynne.

"There are millions of people in the United States who feel that they were not being treated fairly, that they were being left behind," she said.

During the election campaign, Wynne made no secret of her disdain for Trump and his platform.

This spring, she slammed Trump as a candidate who was "dangerous for Canada."

She also said a Trump presidency would be "destabilizing for the continent."
