Canada's aviation regulator has certified the remaining Gulfstream private jet models that US President Donald Trump claimed the country had previously declined to approve. The certification move comes after Trump threatened retaliatory tariffs and other measures against Canada for what he characterized as unfair treatment of American aerospace manufacturers.

Transport Canada issued the approvals for the remaining Gulfstream models, effectively ending a dispute that Trump had escalated through public statements and tariff threats. The certification process had been ongoing, but Trump's intervention accelerated the timeline. The Gulfstream jets in question are produced by General Dynamics and represent a significant portion of the US aerospace manufacturer's business in the Canadian market.

The certification resolves a diplomatic and trade dispute that threatened to escalate into broader economic retaliation. By approving the jets, Canada has avoided potential tariffs on other goods and maintained positive trade relations with the United States. The move demonstrates how aerospace certification can become entangled in broader trade negotiations between neighboring countries.
