Of course he is. By 2026 the other parties will have new leaders (or at least leaders who theoretically have seats in the house) and they will be itching to pull the trigger. That's how minority governments work. You're probably too young to remember this, but PC leader Joe Clark had his minority government (that won in May) get toppled in December by the defeat of his budget. Now, will that happen to Carney? Probably not. But, on average, a minority government lasts about 18 months, so I think we can all expect to see another election in 2026 or early 2027.
BUT....here's the thing: Do you think the NDP/Bloc or Greens want to trigger a new vote that quickly? Sure, they might believe they could win more seats and want to take advantage. But, there is also the horrible reality that Carney might actually do a great job, and triggering an election might give him a solid mandate, so they will delay for a bit longer. Or, will Carney just dissolve parliament to to get that majority. Harper did that back in the day.
The point here, is that while the right will shit of Carney for literally anything right now, most Canadians aren't that partisan and are willing to see what he accomplishes. I mean, just today he unveiled his plan to fast-track projects cabinet deems to be in the national interest. Does this mean Alberta gets its long-wanted pipeline to the coasts? Yeah, I think it does. Does this change how Alberta and Saskatchewan votes? Maybe (probably not).
