New Democrats are kicking off a three-day caucus retreat today in Montreal, days after leaving the supply-and-confidence agreement with the Liberals. Leader Jagmeet Singh announced on Wednesday that he had "ripped up" the agreement with the minority government. Singh says the Liberals are too weak to fight for Canadians and can't stop the Conservatives, offering himself as a credible alternative to Pierre Poilievre. The retreat is also happening in one of the two cities where the N-D-P is hoping to win a byelection on September 16th.

Prime Minister Justin Trudeau is also expected to address his caucus as a whole for the first time since several of his MPs have expressed privately and publicly that he is not the person to lead the party into the next election. NDP caucus meets after leaving deal with Liberals

Former Bank of Canada governor Mark Carney will present his vision for the Liberals' economic policy when he meets with MPs in Nanaimo, B.C., today. The party announced Carney's new role as chair of a Liberal task force on economic growth as MPs arrived for the caucus retreat Monday, where they are planning their strategy for the upcoming election year.
