As the House of Commons reconvened, Prime Minister Justin Trudeau and Conservative Leader Pierre Poilievre engaged in a heated debate over the federal carbon tax, with Poilievre criticizing the government's planned increases and calling for an election on the issue. Poilievre argued that the tax exacerbates poverty and does not address climate concerns, while Trudeau accused him of prioritizing his political agenda over Canadian needs. The session marked the first meeting since the New Democrats ended their support agreement with the Liberals, raising the possibility of a snap election. Meanwhile, a significant byelection in Winnipeg's Elmwood—Transcona riding is underway, with the NDP expected to retain the seat amid competition from Conservatives. The outcome will serve as an indicator of the NDP's strength following a long-held position in the area. The dynamics of the fall session suggest a contentious period ahead in Canadian politics.
