Look, I'm not going to re-litigate all of Trudeau's foibles and mistakes. But businesses not re-investing in themselves pre-dates Trudeau. Even when Harper was PM and the CAD was at or above the USD, few companies put out the cash to upgrade equipment. And, while it is easy to blame former PMs (and some of it is justified), the tariffs have caused a huge amount of uncertainty in the Canadian economy. As mentioned, look at how the US automakers are pivoting to moving production to the US. If you're a Canadian part maker like Magna or Linamar, you might hold off on some capital upgrades.
And, I don't understand where you think I have TDS. The reality is he's thrown a monkey wrench into global trade, and hasn't really accomplished much for it. As a significantly smaller economy to the US, we only have so much we can do. These are facts, and one of the reasons why Carney has been working to expand Canada's international reach in trade. I also think that there are many on here, yourself included, that want to go for the simplest answers. It is easy to blame Trudeau but neglect what Harper did. It is easy to say immigration is a major cause of stuff when there has been historic under-investment by Canadian companies for decades. But, as I've said, none of these issues are simple and easy to solve. The problems are not from one policy decision or something that was done in the last decade.
