The Bank of Canada on Wednesday trimmed its key policy rate by 25 basis points to 3%, cut growth forecasts and warned Canadians that a tariff war triggered by the United States could cause major economic damage.

The Bank of Canada on Wednesday cut its benchmark rate for a sixth straight time, and warned of a significant shock to the economy from a U.S.-Canada trade conflict with tariffs of up to 25%.

“A long-lasting and broad-based trade conflict would badly hurt economic activity in Canada. At the same time, the higher cost of imported goods will put direct upward pressure on inflation,” Bank of Canada Governor Tiff Macklem said in a prepared opening statement on Wednesday.
