After a summer of rodeos, dinosaurs and door-knocking, Pierre Poilievre is now officially heading back to Ottawa as a Conservative member of Parliament for Alberta.

The Tory leader will represent the sprawling rural riding of Battle River—Crowfoot, in the province's eastern region, after winning a byelection on Monday. 

"Getting to know the people in this region has been the privilege of my life," Poilievre told a crowd at a victory party in Camrose, Alta., on Monday night. "In fact, I've had a hell of a lot of fun."

Air Canada cancelled hundreds of additional flights on Sunday after the union representing its flight attendants announced the workers would remain on strike in defiance of a back-to-work order.

The Canadian Union of Public Employees said it filed a challenge in Federal Court on Sunday to an order by the Canada Industrial Relations Board that said its members must return to work by 2 p.m. ET.

"Our members are not going back to work," CUPE national president Mark Hancock said outside Toronto's Pearson Airport. "We are saying no."

Ukraine and its allies held a virtual meeting Sunday as President Volodymyr Zelenskyy prepares for a high-stakes discussion with U.S. President Donald Trump in Washington, D.C., on Monday.

Prime Minister Mark Carney's office said in a Sunday afternoon statement that he took part in the call with the "Coalition of the Willing," a group of nations that have agreed to support Ukraine as it defends itself against Russian's full-scale invasion. The statement did not indicate that Carney would be part of Monday's discussions.

Conservative Leader Pierre Poilievre has set his sights on Canada's electric vehicle mandate, pledging Thursday that his party will embark on a national campaign to push the Liberal government to scrap the policy he's dubbed the "Carney tax."

Poilievre led the charge as the Conservatives relentlessly attacked the consumer carbon price over the last two years, with the Liberals admitting the Tory tactics swayed public opinion and forced them to end the so-called carbon tax earlier this year. 

Reproductive health advocates say the federal government's failure to commit to funding pharmacare in all provinces and territories is leaving people with a lot of uncertainty, and could create inequality across the country.

"It's really disappointing, honestly," said Liz Thompson, advocacy lead for Cover Contraception.

"It seems like they don't really know what they're going to do."

The Canadian Nurses Association says it hopes the new "united Team Canada" approach at the Council of the Federation will lead to harmonization of nurses' licences across the country.

The association was among a number of health-care advocacy groups at the recent annual meeting of Canada's premiers.

While health care tends to take centre stage when the premiers meet, this year's gathering with Prime Minister Mark Carney was dominated by discussion of U.S. President Donald Trump's global trade war.

The 2025 wildfire season is already one of the worst on record for Canada and there is a high risk that more fires will break out in August, federal officials said on Friday.

More than 5.5 million hectares of land have burned so far this year, more than double the 10-year average for mid-July.

That is still well behind the record fire season in 2023, when more than 6,000 fires burned more than 15 million hectares of land.

There were 561 fires burning as of Friday, including 69 that were considered out of control.

Prime Minister Mark Carney's chief of staff and the country's top public servant will be responsible for maintaining an ethics screen preventing him from making decisions that benefit his former employer, says a disclosure issued by the office of the ethics commissioner on Friday.

Ottawa is giving no sign that it intends to amend existing legislation on medical assistance in dying — something a UN committee called for earlier this spring.

The federal minister responsible for disabilities spoke at a hearing of the United Nations Committee on the Rights of Persons with Disabilities last week, about two months after the committee called on Canada to repeal the 2021 law that expanded eligibility for assisted dying to those whose deaths were not reasonably foreseeable.

The Liberal government has introduced legislation aimed at cutting down barriers to internal trade by recognizing provincial and territorial rules at the federal level.

Officials who briefed reporters this morning say the goal is to reduce the number of redundant standards across the country.

They say that, for example, a company that produces washing machines that meet a provincial energy efficiency standard won't have to meet a separate federal standard to sell outside that province.
