The letter arrives just days ahead of a self-imposed July 21 deadline for a trade resolution, which both countries agreed to during the G7 Summit in Alberta last month.
As reported by BNN Bloomberg, the letter said tariffs “may be modified, upward or downward, depending on our relationship with Your Country.”
In the letter, Trump tied the tariffs to Canada’s handling of fentanyl, the trade deficit, and the supply management system.
“If Canada works with me to stop the flow of Fentanyl, we will, perhaps, consider an adjustment to this letter,” he stated.
The move follows earlier US tariffs targeting Canadian steel, aluminum, and autos, as reported by BBC, with specific levies of 25 percent on non-CUSMA-compliant goods and 10 percent on energy and potash.
