Bombardier takes its wing maker in-house. What aerospace consolidation means for Canadian suppliers.

Bombardier is acquiring MHI Canada Aerospace's Mississauga wing plant and its roughly 750 workers. Vertical integration at the prime reshapes where the rest of the aerostructures supply chain fits.

On September 1, 2026, Bombardier and Mitsubishi Heavy Industries announced that Bombardier will acquire the assets of MHI Canada Aerospace (MHICA) in Mississauga, Ontario. The purchase price and other terms were not disclosed. The deal is subject to regulatory approvals and customary closing conditions, with closing expected later in 2026.

The scope is specific. Bombardier is taking on about 750 employees, a 270,000 square foot manufacturing and assembly facility and a 70,000 square foot logistics centre. The plant builds wings for three current business-jet programs: the Global 5500, Global 6500 and Challenger 3500. MHI will provide transitional support after closing.

Why a prime buying its wing maker matters downstream

A prime bringing a major aerostructure in-house is vertical integration: it moves work that sat with a supplier onto the prime's own books. That does not shrink the aerospace supply chain, but it reshapes it. The prime still buys machined parts, assemblies, tooling, fixtures and finishing from a tier-2 and tier-3 base. What changes is the expectation. As primes consolidate critical structures, the suppliers that keep winning the rest are the ones already qualified to aerospace standards who can prove it.

What this means if you source aerospace parts in Canada

Aerospace work runs on documented quality. AS9100 is the baseline, NADCAP accreditation governs the special processes (heat treat, non-destructive testing, coatings, chemical processing), and first-article inspection and full material traceability are expected, not optional. The parts are often in superalloys and titanium held to tight tolerances on 5-axis machines. If you are sourcing into an aerospace program, the practical read is that the qualified Canadian supplier base matters more as primes integrate, not less, and the shops that can take the work are the ones already carrying AS9100 and the right NADCAP accreditations.

FAQ

What certifications does aerospace parts work require?

AS9100 as the quality baseline, NADCAP accreditation for the special processes a part needs (heat treatment, non-destructive testing, surface finishing, chemical processing), and first-article inspection with material traceability. The exact set depends on the part and the prime's flow-down requirements.

Does Bombardier buying MHICA reduce work for other shops?

It moves wing production for three programs in-house, but primes still source machined parts, assemblies, tooling and finishing from a tier-2 and tier-3 base. The effect is a higher qualification bar for the suppliers that win the remaining work, not the disappearance of that work.
