Amid Conservative leader Pierre Poilievre’s calls for a “carbon tax election”, two leading Liberal leadership candidates are dropping the Trudeau policy.

Former Bank of Canada governor Mark Carney is expected to formally announce his bid to replace Prime Minister Justin Trudeau late next week, a source close to his campaign told CBC News.

Carney disclosed his intentions to a crowd in Edmonton, Alberta, the western Canadian city where he spent the bulk of his youth, promising an economic agenda focused on lifting the country from a period of stagnant growth.
