Trump threatens to hit Canada with 35% tariff next month if country does not help with fentanyl

“If Canada works with me to stop the flow of Fentanyl, we will, perhaps, consider an adjustment to this letter,” Trump wrote to Carney. “These Tariffs may be modified, upward or downward, depending on our relationship with your Country.”

President Donald Trump on Thursday sent Canadian Prime Minister Mark Carney a letter notifying him that he would impose a 35% tariff on Canadian goods next month if the country doesn't step up in battling fentanyl.

Trump has been sending tariff rate cards out to countries this week that have not reached a trade deal with the United States. The letters have largely been going out to seven countries at a time. 

The president argued that Canada has not done enough to help with the illegal flow of fentanyl that has been smuggled into the U.S. through the northern border. The U.S. is facing an opioid epidemic, and fentanyl is considered one of the most dangerous opioids in the country.

“If Canada works with me to stop the flow of Fentanyl, we will, perhaps, consider an adjustment to this letter,” Trump wrote to Carney. “These Tariffs may be modified, upward or downward, depending on our relationship with your Country.”

The U.S. previously imposed a 25% tariff on Canada, but delayed the tariffs while trying to reach a trade agreement. However, the new tariffs will go into effect on Aug. 1. 

It is not clear if products covered under the 2020 trade agreement between the U.S., Canada and Mexico will be excluded from the tariffs or not.
