As a Detroit native and current resident of the city, I've had a front row seat to what Donald Trump's proposed tariffs are doing to U.S. relations with Canada, not to mention his recent comments about turning it into the 51st state.

In fact, there may be no better real-time example of the deterioration than the long-standing bond

between my hometown and its neighbor across the river, Windsor, Ontario.

As the auto parts capital of Canada, Windsor's economy and identity has for decades been linked to the Motor City.

According to government data, Ontario has more than 100,000 automobile jobs, not counting the

spin-off jobs. And the two populations have enjoyed a very friendly symbiotic relationship

since way back before my time.

But consider this. As Trump threatens to annex one of the U.S.'s closest allies and hit products

crossing the border with 25 percent tariffs, the historic harmony between these two sister cities is already starting to fray as

Windsor residents deal with Trump's policies and rhetoric.

under the Ambassador Bridge,

where we could look across the Detroit River to Canada, not even a half mile away.

This is the busiest commercial border crossing in North America.
