Canadian Conservative leader Pierre Poilievre faces a crucial test of his leadership this week, but what lies ahead is a bigger challenge: convincing Canadians that he is the best person to guide the country through its uncertain future.

Party delegates will vote on whether Poilievre should remain leader on Friday at the Conservative convention in Calgary. It is part of an automatic review that is triggered after an election loss - in this case, Poilievre's defeat last April.

Poilievre appears to have wide support heading into the convention, party members have told the BBC, and is expected to win handily.

But he has struggled to broaden his post-election appeal beyond the party and against Prime Minister Mark Carney, especially on how to handle US President Donald Trump. That is an issue front of mind for many Canadians.

At the convention, winning anything above 80% in his leadership review will be considered a success for Poilievre, said David Coletto, founder of polling firm Abacus Data.
