As former finance minister Chrystia Freeland prepares to launch a Liberal leadership bid, a source close to her says scrapping the controversial consumer carbon tax will be one of her policy planks.

The source, who was not authorized to speak publicly about the announcement, also said Freeland’s first policy promise will be to impose dollar-for-dollar retaliatory tariffs on U.S. imports to match the tariffs U.S. president-elect Donald Trump has vowed to impose on Canada.
