President-elect Donald Trump’s tariffs would spell disaster for U.S. Markets, according to Ontario Premier Doug Ford. Ford emphasized the negative impact of such tariffs on the economy.

Ford said tariffs won’t work due to how integrated the U.S. and Canadian economies are. He brought up the auto industry, which has deep ties in Michigan and Ontario.

Market experts warn that the tariffs could lead to increased prices for consumers.

Businesses in Ontario are particularly worried about the consequences of Trump’s trade policies.
