The right-leaning United Conservative Party (UCP) has taken power in the oil-rich Canadian province of Alberta, routing the left-leaning NDP, BBC reports.
The UCP won 62 of the 87 seats of the legislature, provisional results say.
Leader Jason Kenney, a former federal cabinet minister, will be the next premier of Alberta.
The win could reverberate beyond Alberta, setting the party on a collision course with PM Justin Trudeau's Liberals over climate change.
Mr Kenny has vowed to do away with a provincial carbon levy and to join a handful of other provinces fighting the federal government in court over its carbon tax.
