Why did you casually jump to per capita GDP? Per capita GDP is finally going up after a long regression, and one of the reasons Canada slipped to a very small recession is that hundreds of thousands of migrants are leaving the country, their visas expired. When you remove a lot of people that were consuming housing and food and cell plans and delivery doordash, GDP drops.
You have two conflicting complaints simultaneously, and you should make up your mind. Were you happy when Canada's GDP was increasing courtesy of mass migration?
So are you happy with the changes? I'm super happy with it. I'm also quite pleased with how well Canada has weathered a criminal felon pedo that has tried his hardest to hurt us, many Americans blissfully oblivious.
And yup, the many tentacles are government are going to keep making laws and planning trains and doing pipeline projects and countless other programs -- they aren't restricted to whatever the imaginary pet is of a particular complainer -- and amazingly they can competently do all of this simultaneously! Not always in a way that everyone agrees with, though.
Per-capita GDP rose mainly because of what you said, declining immigration growth.
The issue is that our economy has been in decline for years, increasing the population dramatically masked that at, least in nominal GDP, and as population growth declines it reveals the weaknesses that were previously obscured. Simply reducing population growth is not enough to fix the last 10 years. Immigration was and is never the problem with our economy, a lack of real growth is.
So no, I wasn't happy when our GDP rose because of population growth, and I'm not happy today either because pulling a few levers on the immigration machine to change the numbers slightly doesn't fix anything. And it doesn't appear like the government is doing anything to fix it, instead focusing on the stuff we're talking about in this thread.
