The Conservatives raised more than $4.4 million between April 1 and June 30, while the Liberals raised nearly $2.8 million and the New Democrats received nearly $1.2 million in contributions. Financial returns filed with Elections Canada also show contributions to Conservative federal leadership candidates in the second quarter totaling more than $8 million. Front-runner Pierre Poilievre received the most contributions of the candidates vying for the party leadership. Poilievre raised just over $4 million, while former Quebec premier Jean Charest raised nearly $1.4 million for the race. The fundraising results come on the eve of the final party leadership debate on Wednesday night. Charest, Roman Baber and Scott Aitchison are scheduled to take part in the 90-minute event that begins at 6 p.m. ET. The two other candidates in the contest, Poilievre and Leslyn Lewis, announced last week that they would join the debate. The Conservatives have until September 6 at 5pm. ET to mail the envelope containing their ballots. The winner will be announced on September 10th.
