Back home for the first time since the start of the campaign, Pierre Poilievre, the Conservative leader seeking to become Canada’s next prime minister, fired up his most ardent supporters with his greatest hits.

Thousands had come to a cavernous building in an industrial park in central Alberta, many parking by the roadside and walking the last mile or two, in what was the politician’s biggest rally yet.

He railed against an economy that he said was “a transfer of wealth from the have-nots to the have-yachts.” He whipped up thunderous applause with his vow to “cut foreign aid to dictators, terrorists and global bureaucracies, to bring our money home.”

He pledged that Canada’s beefed-up armed forces would be “guided by a warrior culture, not a woke culture.” His promise to eliminate the CBC, the public broadcaster he has accused of liberal bias, drew some of the most sustained applause.

“I love you, too,” Mr. Poilievre said after a long pause and a sip of water. “I love you, I love you, I love this province.”

Alberta, the oil-rich province in Western Canada, is the birthplace both of Mr. Poilievre, 45, and the right-wing populist movement that has come to dominate Canada’s Conservative Party.
