Alberta’s Progressive Conservative government is about to face its first real test under Premier Jim Prentice: it’s by-election day in the province.

Four ridings are up for grabs: Calgary Elbow, Calgary Foothills, Calgary West and Edmonton Whitemud.

Two high-profile cabinet ministers and Prentice himself will try to earn a seat in the legislature.

Experts at Mount Royal University believe some of these races are still too close to call.

Among them is Political Scientist Lori Williams, who tells City News Calgary Elbow is shaping up to be a four-way race.

“I think those who support the policies will probably still vote for the Conservatives and the question is for those who don’t support the government and they want to send a message, who are they going to vote for? And some of those ridings, the anti-Conservative vote might get split,” Williams said.

Her colleague, Keith Brownsey, says voters often see by-elections as a chance to punish governments and the Wildrose needs to win at least one seat.

“Now if the Wildrose can’t do that, they can’t win at least one, they’ll have to question their leader, question their tactics and go as far to ask whether or not they should be there as a political party,” he said.

Polls will close at 8 p.m. Monday, and 660News will have complete coverage of the results.
