Quick Summary

Conservative MP Scott Aitchison announced his resignation at the end of the fall session, becoming the eighth Conservative MP to leave in the last year. Despite winning his northern Ontario riding by 10 points last year, Aitchison's departure signals a decline in the party’s national support, with polls now showing lower public esteem for the Conservatives under Pierre Poilievre's leadership. Aitchison's decision reflects his discomfort with the current direction of the Conservative Party and its alignment with more extreme factions, as evidenced by his previous criticism of the Freedom Convoy movement.

Story summary

Scott Aitchison, a Conservative MP for Parry Sound—Muskoka in Ontario since 2019, is expected to resign his seat by the end of the fall parliamentary sitting this year. Sources indicate that Pierre Poilievre, leader of the Conservative party, was informed last week about Aitchison's intention to leave. Aitchison had previously run for the party leadership in 2022 but finished fifth.

Aitchison's resignation will bring the total number of Conservative MPs leaving since the start of this year to eight and add another vacant seat to the House of Commons, where six seats are already empty. The riding he represents was considered a relatively safe Conservative seat; however, current polling suggests it could flip to Liberal control if there were an immediate by-election.

The announcement comes amid growing concerns within the party about its public image and declining popularity since Poilievre's leadership took over in 2025.

🔮 When Sentinel R&D, a Hamilton, Ont.-based defence firm, signed a deal with a Ukrainian drone firm, Airlogix, in May, the response from the Kremlin was unusual.
🔮 A meeting to that end was attended by representatives of 70 institutions on Monday, with the goal of creating a national strategy that might turn the tide. Gabriel Miller, president of Universities Canada, said universities have done work at ground level to improve policies to protect Jews and fight antisemitism by beefing up campus security, improving training in diversity offices, and so on.
🔮 LFI politicians turned up to support some protests, including the left-wing mayor of Saint Denis in the northwestern suburbs of Paris, Bally Bagayoko, who was filmed dancing with students, while garbage cans burned in the background.
🔮 The first was the people of Alberta, who will be asked on Oct. 19 to vote on whether the province should remain in Canada, or whether it should negotiate to hold a binding referendum on independence.
🔮 The Conservatives will try to spin the departure of Scott Aitchison, the popular MP for Parry Sound–Muskoka, as being of negligible importance.
🔮 U.S. President Donald Trump told reporters in the White House on Monday that he thinks a trade deal with Canada that gets rid of tariffs will be struck, possibly within three to four weeks.
🔮 (But) we’re trusting this man with massive changes that will accelerate projects at the cost of Indigenous rights, at the cost of the environment, and at the cost of protections for workers, including the fundamental right to strike.”
🔮 Sooner or later, he will come down to earth with a bump – quite possibly because he has decided to expend some of the political capital he has accumulated.
🔮 When Norway’s prime minister, Jonas Gahr Støre, meets with Prime Minister Mark Carney in Ottawa next week, the subject of farmed salmon will be high on the agenda.
🔮 But Carney seems supremely uninterested in Parliament and likely views an election campaign as a distraction. The same could not be said for the political people around him.
