Pierre Poilievre faces a leadership review as Conservatives gather in Calgary.

Conservative delegates are meeting in Calgary and will vote on whether leader Pierre Poilievre should remain in his role; it is the first such vote since 2005.

Conservatives from across Canada are meeting in Calgary for the party's national convention this weekend. For the first time in two decades, delegates will vote on whether Pierre Poilievre should remain as party leader. The last leadership review of this kind took place in 2005, when Stephen Harper received 84 per cent support from delegates. Party observers are watching Poilievre's scheduled speech on Friday for indications about his approach going forward.
