Senator says tariffs a wake-up call for Canada

Sen. Chuck Grassley said U.S. President Donald Trump's threat to hit an array of Canadian goods with new tariffs should serve as a "wake-up call to Canada to make some changes."

The Trump administration said in July it would not be extending CUSMA for another 16 years. That triggered an annual rolling review process that will continue for a decade, at which point the deal would expire if the three countries do not agree on an extension.
