VANCOUVER, British Columbia: Prime Minister Mark Carney said Thursday that Canada is intensifying negotiations with the United States to reach a comprehensive trade deal but is prepared to respond should President Donald Trump’s threat of 50 percent tariffs on Canadian goods go into effect. The new tariffs, announced by Trump on Monday, are scheduled to come into effect Aug. 19.

The Canadian leader’s carefully worded statement stopped short of threatening retaliatory tariffs but warned that the move would raise costs for American families.

The White House says the tariffs will go into effect in 30 days, meaning there is time for negotiations.
