Less than five weeks after she resigned her cabinet seat over a dispute with Prime Minister Justin Trudeau, Chrystia Freeland has launched her campaign to replace him as the leader of the Liberal party.

In a sparsely worded post on the social media platform X, the former finance minister and deputy prime minister said simply that she's "running to fight for Canada."

Newfoundland and Labrador Liberal MP Ken McDonald said he personally credits Freeland for reversing the decision to impose the carbon tax on home heating fuel, which mostly affected Atlantic Canadians and was widely seen as a blow to the carbon tax policy.
