That is not why the Carney administration made this choice. You are more focused on the immediate term situation, whereas they are more focused on the future steady state. They are taking an immediate term hit, with the belief that it will lead to a better steady state later.

The future is unknowable, so that might be the wrong bet. But in my view, it is the right one, in no small part because the political situation is on their (that is, the Carney administration's) side. Political support is what determines the ability to withstand pain. In Canada there is currently far more solidarity with the administration's stance on standing up to US bullying than there is in the US for the Trump administration's (many) price-increasing policies.

If the political situation were reversed, this would probably be a bad idea for Canada! But it isn't, so it isn't.
