What’s the connection between the two most intertwined economies on planet earth?

That looking at monthly numbers is stupid? The US has had significantly more job growth in 2026 than Canada has. The July numbers are convergence to a roughly common mean.

Canada is currently on the short list of countries Trump throws into his usual mad-libs of grievance flavored policy making.

It doesn't need a connection (even tho there are many). The US/Trump is going after Brazil for creating a payment system.
