The first polls in the Canadian election will close within minutes, providing an indication of who will be elected prime minister and lead the fight against Donald Trump’s trade war.

Ballots in Newfoundland and Labrador  will be tallied after voting stops at 7pm ET, as Mark Carney faces an anxious wait to see if his Liberals will win enough seats for him to remain the country’s leader.

Polling suggests that he will win more seats than Pierre Poilievre, the Conservative leader, but it is unclear whether Mr Carney will be able to form a majority government after he called a snap election last month.

The largest swathe of seats up for grabs are in Ontario and Quebec, where the Liberals are predicted to put on a strong showing when polls close at 9:30 ET.

The race has been upended by Mr Trump’s declaration of a trade war on Canada and his repeated desire to annex the US’ northern neighbour as its “51st state”.

Mr Poilievre’s Conservatives, long 20 points ahead in the polls, have seen their support collapse as Mr Carney ratcheted up his anti-Trump rhetoric, although the race between the two parties is seen to have narrowed in the final few days.

Polling averages from CBC suggest the Liberals will take a 17-seat majority in the Canadian House of Commons.
