The JT government run has been mostly non-catastrophic, like mostly peaceful gatherings where only a few people out of thousands get shot, mostly good drivers that only careen off the road in heavy rain, etc.
It is normal to judge governments by how they perform under pressure during more difficult periods, and to expect them to do perform adequately all the time, not some of the time.
I'm not sure there is a precedent in the modern era in Canada for the level of fiscal management of the past 3 years. I would argue that even before the +16% debt-to-GDP of 2020-2021, the federal government was not prudent in the comparatively good years and so they created an environment where they had less wiggle room during bad years. The Harper government had flat debt-to-GDP from 2006-2015 and they had the global financial crisis in the middle of that. During the Chrétien and Martin years the debt was paid down considerably. It is hard to accuse people of being partisan when they praise Paul Martin but don't think the Justin Trudeau era has gone well as of 2023. If they just want good fiscal management regardless of party that's the definition of non-partisan, while we have some turbo partisans on here who love the Liberals no matter what happens.
