Even without a trade war, Canada should be trying to import less american made products because of the poor quality. Inferior health regulations. Steroid and hormone filled dairy and meat. American processed foods are excessively filled with sodium and sugar. Everything american made in the grocery store should be avoided.
I've had terrible performance and reliability with every american made product I've ever purchased. Electronics, clothing, furniture. I'll never buy another american made car.
Just based on quality, Canada should be importing less US products. "Made in the USA" is a red flag for me.
