Canada’s Liberal Party won a fourth term in office but appeared short of a majority in Parliament, which could force Prime Minister Mark Carney to seek help from rival politicians to push through an economic agenda designed to contain fallout from President Trump’s trade war.

Preliminary estimates early Tuesday from Elections Canada, the government body overseeing elections, indicate the Liberals had 43% of the popular vote, compared with 42% for the Conservatives. The Liberals won or were in the lead in 168 of the 343 seats in Parliament. Pollsters had predicted a Liberal majority, but the Conservative Party outperformed expectations in Ontario, especially in the suburbs around Toronto. Votes were still being counted and several close races had yet to be called.
