Canada's Liberal Party will announce Prime Minister Justin Trudeau's successor on Sunday as both party chief and head of the country's government in the midst of a trade war with the United States that could cripple the Canadian economy.

Canada's governing Liberals will announce a replacement for Prime Minister Justin Trudeau on Sunday as the country deals with U.S. President Donald Trump's tariff threats and as a federal election looms.

Prime Minister Justin Trudeau said Thursday he welcomed indications that the U.S. would delay substantial tariffs on Canadian products for a month, but said Canada’s plan to impose retaliatory tariffs would remain in place for now.
