As millions of voters head to the ballot box in the United States today, people in Saskatchewan are asking themselves which candidate would best serve the province's interests.

University of Saskatchewan political studies professor Greg Poelzer believes Canadian leaders would be able to work more closely with a Hillary Clinton presidency. That includes Premier Brad Wall, who Poelzer notes has ties to the United States.

"On things like carbon pricing, if we're going to get there successfully in Canada, we may need to negotiate that on both sides of the border," he told CBC Radio's Saskatoon Morning on Tuesday.

"There is an unfair advantage for American producers in the oil field or agricultural producers, and we could have negotiations taking place between the two administrations."

When it comes to trade policy, Poelzer said there's no contest.

"[Donald] Trump would be a disaster for our province," Poelzer said. "You can see Trump saying, 'Saskatchewan farmers are ripping us off. It's unfair. They have devalued currency.'"

Poelzer believes trade would be much more stable if Clinton were elected.

"We'll be able to maintain NAFTA, which is critically important, especially for a trading province like Saskatchewan," he said.

"Even on the TPP [Trans-Pacific Partnership], she [Clinton] was the architect driving it originally. When the final details came out, she said it didn't meet her standards. But what she's done is, she's created some wiggle room. You could imagine it being tweaked here or there, and say now it meets her standard."

Even though Clinton has spoken against projects like the Keystone XL Pipeline, Poelzer still believes that project has a better chance to succeed under her than Trump.

"Trump has put a qualifier on his support," he said. "He wants to make money off of that pipeline ... It's not an unencumbered position on Keystone for Trump, and that's something that people have missed."
