U.S. President Donald J. Trump ignited a fresh transborder trade skirmish late Thursday, declaring the decertification of Bombardier Global Express jets and all Canadian-made aircraft until Transport Canada approves Gulfstream’s G500, G600, G700 and G800 models. In a pointed Truth Social post, Trump accused Canada of “wrongfully, illegally, and steadfastly” blocking these “greatest, most technologically advanced airplanes ever made,” produced by General Dynamics-owned Gulfstream in Savannah, Georgia. He further warned of 50% tariffs on any Canadian planes sold into the U.S. if the impasse persists.
The move thrusts the ultra-long-range business-jet arena into the crosshairs, where Bombardier and Gulfstream vie fiercely for dominance among high-net-worth clients seeking intercontinental range and luxury. Bombardier edged Gulfstream in 2024 deliveries, producing 146 units to Gulfstream’s 138, though the American rival posted higher billings of $8.3 billion against $6.3 billion, per a 2025 General Aviation Manufacturers Association report.
Certification underpins aviation safety worldwide, with the designing nation’s authority—here, the FAA for Gulfstream—issuing primary type certificates validated abroad via bilateral agreements. Transport Canada has certified older Gulfstream models like the G450, G350, GV, G550 and G500 to varying degrees, as noted by CBC News. Yet the newer quartet lags: G500 FAA-certified in 2018, G600 in 2019, G700 in 2024, and G800 in April 2025 alongside EASA approval, but no matching nods from Ottawa, according to multiple reports including Flight Global.
Certification Delays Fuel Presidential Fire
Transport Canada officials maintain the process involves rigorous paperwork review, not outright refusal. Aviation consultant John Gradek told The Globe and Mail, “We haven’t decertified the Gulfstream; we are looking at the paperwork. That’s what’s taking time now.” Older models operate in Canada—21 Gulfstreams appear in the civil aviation database—yet full type certification for the disputed lineup remains pending amid post-Boeing 737 Max scrutiny slowing global approvals, as Flight Global detailed.
Trump’s decree targets Bombardier’s Global Express family first, with 150 units registered in the U.S. across 115 operators, per Cirium data cited by Reuters. Broader fallout could ensnare 5,425 Canadian-built planes in U.S. service, from regional jets to helicopters. Bombardier responded cautiously, noting it had “taken note” and was engaging Ottawa, while stressing thousands of its jets fly daily stateside, according to CBS News.
The FAA holds decertification authority for safety lapses, not trade disputes, raising questions on implementation. Past presidents deferred to the agency; Trump appointees now helm it. No immediate FAA comment emerged, but revocation could ground fleets absent exemptions, hammering maintenance and resale values.
Rivalry in the Stratosphere
Bombardier’s Global series, flagship of the Montreal stalwart, competes directly with Gulfstream’s offerings in speed, range and opulence. The freshly FAA-certified Global 8000 hit Mach 0.95—fastest civilian jet since Concorde—while Gulfstream’s G800 touts 8,000-nautical-mile legs. Bombardier outproduced rivals yearly but trails in revenue since 2012, per industry tallies. This feud echoes 2017, when Trump-era duties hit Bombardier’s CSeries (now Airbus A220) over subsidy claims.
Canadian Premier Mark Carney’s office stayed silent initially, amid pushes to diversify exports as U.S. absorbs 70% under USMCA. Carney lately decried eroding rules-based trade, per Reuters. Tariffs at 50% would spike costs for U.S. buyers, from private owners to feeders like American Airlines’ 200 CRJs.
Executives at both firms held back public retorts. Gulfstream President Mark Burns touted U.S. manufacturing in November remarks covered by CBC News. Bombardier, post-private-jet pivot, eyes growth but faces U.S. market jeopardy.
Trade War Echoes and Market Ripples
Wall Street watched warily: Bombardier shares dipped in after-hours, Gulfstream parent General Dynamics steadied. Analysts flag risks to supply chains, with Canadian parts integral to U.S. assembly. CNBC highlighted Airbus A220 uncertainty, built in Mirabel. Broader aerospace ties, from Pratt & Whitney engines to regional jets, hang in balance.
Diplomats eye bilateral aviation pacts for resolution, but Trump’s timeline demands “immediate” action. History suggests negotiations: prior spats yielded deals. Yet with Carney eyeing diversification and Trump wielding tariff cudgels, this jet clash tests USMCA resilience amid certification norms.
Operators brace: resale values for Globals could crater, Gulfstream sales to Canada stall. Insiders peg billions in play, reshaping who flies what across North America.
