() Canadian Prime Minister Mark Carney is meeting with President Donald Trump Tuesday as the two countries have yet to reach a trade deal.

The White House is set to review a critical free-trade agreement next year and Canada, where 77% of exports go to the U.S., has yet to reach a deal to lower tariffs.

Trump has also made repeated comments about making Canada the 51st state, creation tension in a normally strong alliance.

“We’ve had ups and downs, but this is the lowest point in relations that I can recall,” said Frank McKenna, a former Canadian ambassador to the United States and current deputy chairman of TD Bank.

“Canadians aren’t being instructed what to do. They are simply voting with their feet,” he said. “I talk every day to ordinary citizens who are changing their vacation plans, and I talk to large business owners who are moving reward trips away or executive business trips. There is an outright rebellion.”

Steel and aluminum are two areas where Canada is likely to seek relief from Trump’s stiff tariffs.
