Former finance minister and deputy prime minister Chrystia Freeland is expected to announce a bid for the Liberal leadership within the week, sources have told Radio-Canada.

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.
