While I sympathize with your sentiment, you need to include a more realistic model of how trade works. But, if you really want to look at it, international trade economists admit to not understanding the system as it is today. The ecosystem is so complex that tinkering with it is actually a risk. I think the Covid situation might actually be informational, as people examine what happened to supply lines during the pandemic.
With your proposal, for example, you are banning iPhones. Are you going to allow trade with the US where components parts come from China anyway ? And what about Chinese companies IN Canada ? What are we going to do with our exports ? Our coal mines can't really be repurposed to create cat food, right ?
I would very much like to pursue this topic, but we really need someone with a deep knowledge of trade. I know a bit, but only enough to ask questions and point out contradictions.
Thanks for your post.
