Trump Threatens decertification of Canadian Aircraft and 50% tariff amid Gulfstream dispute.
Washington — President Donald J. Trump said the United States is moving to decertify Bombardier’s Global Express business jet and potentially all aircraft manufactured in Canada, escalating a trade and regulatory dispute centered on aircraft certification and market access.
In a post on his Truth Social platform, Trump also threatened to impose a 50% tariff on Canadian-built aircraft sold into the United States unless Gulfstream Aerospace’s business jets receive full certification in Canada. He argued that Canada’s certification process is effectively blocking the sale of Gulfstream products north of the border.
“Canada is prohibiting the sale of Gulfstream aircraft,” Trump wrote, asserting that U.S. actions would continue until what he described as unequal treatment is addressed.
The dispute focuses on Transport Canada’s certification of Gulfstream models. Several aircraft in the U.S.-based manufacturer’s lineup—including the G350, G450, GV, G550, and G500—have received some level of Canadian certification. However, newer models such as the G600, G700, and G800 remain uncertified in Canada and have become a flashpoint in the president’s remarks.
Bombardier, the Quebec-based aerospace company and a major competitor to Gulfstream in the business jet market, said it is monitoring the situation. In a statement, the company said it has taken note of Trump’s comments and is in contact with the Canadian federal government regarding the remarks.
The White House did not immediately provide details on the timing or scope of any decertification actions or tariffs, nor did it clarify whether measures would apply broadly to all Canadian-manufactured aircraft or be limited to specific models.
Industry analysts said any move to decertify aircraft or impose steep tariffs could have significant implications for cross-border aerospace trade, certification reciprocity, and business aviation operators in both countries. Canada and the United States have long relied on mutual recognition frameworks to streamline aircraft certification, a system that has underpinned decades of integrated aerospace manufacturing.
