12:18 PM EST, 12/16/2024 (MT Newswires) -- The Toronto Stock Exchange is down 95 points at midday, with nearly all sectors lower.

Healthcare is the main gainers, up 0.6%.

Deputy PM and Finance Minister Chrystia Freeland, resigned Monday, citing policy disagreements on with PM Justin Trudeau, adding to the existing jitters and uncertainty around Canadian preparations for a potential tariffs war with the United States in the new year. Housing Minister Sean Fraser also resigned, for family reasons.

This comes as the cabinet was due to meet and came just hours before Freeland herself was due to deliver the federal governments Fall fiscal update. The events of today will lead to a big cabinet re-shuffle, and creates uncertainty around whether the fiscal update -- which is already late -- will even be delivered later today, and if it is by whom. It also creates uncertainty around who is likely to lead the Canadian economics team in the lead up to U.S. President-elect Trump taking office.

Canada media reports say there is talk that former Bank of Canada Governor Mark Carney is being lined up to replace Freeland as Finance Minister as he is seen as a better communicator. Media reports suggest that Freeland, who said in a tweet earlier Monday that she had been offered a different job, was going to be asked to look after the Canada and U.S. relations file instead, but she has turned that offer down.
