Pratt & Whitney Canada‘s Pratt Whitney Canada Longueuil investment of C$275 million will add automated production lines, upgraded machinery and digital manufacturing processes to the company’s global headquarters near Montreal, as demand across regional, business and general aviation continues to build. The announcement was made at the Farnborough International Airshow on 21 July 2026.
Government funding backs the Longueuil modernisation push
The project draws on contributions from both federal and provincial governments alongside the company’s own capital. The Canadian government will contribute up to C$34 million through its Strategic Response Fund, with Ottawa stating the project will maintain 650 jobs and strengthen Canada’s aerospace manufacturing base. The Quebec government will provide a further C$9.9 million, with Pratt & Whitney Canada funding the remainder of the C$275 million total.
The Longueuil site is the company’s principal manufacturing centre. At 1.23 million square feet, it employs nearly 4,500 people and produces components across Pratt & Whitney Canada’s full engine portfolio, including the PT6 family for turboprops, helicopters and business aircraft, the PW100 and PW150 regional turboprop families, and the PW300 and PW500 business jet engines.
‘This strategic investment in Longueuil strengthens our industrial capacity, enabling us to better support our customers and meet growing global demand,’ said Pratt & Whitney Canada President Satheeshkumar Kumarasingam.
The company said the new equipment and processes will improve manufacturing efficiency and precision. No timetable for completing the upgrades was provided, nor did the company specify which engine programmes will receive the additional capacity.
Fleet scale and MRO reach underline the Pratt Whitney Canada Longueuil investment case
The scale of the aftermarket obligation underpinning this capital commitment is considerable. Pratt & Whitney Canada supports a fleet of nearly 75,000 engines operated by about 14,000 customers worldwide. According to RTX, the broader Pratt & Whitney network supports more than 90,000 in-service engines through its global maintenance, repair and overhaul facilities, illustrating the volume of engine activity the expanded Longueuil plant will need to support upstream.
Kumarasingam said the investment reinforces the company’s role in Quebec’s aerospace industry while improving its ability to supply customers around the world. The PT6 family alone powers a wide range of platforms across multiple aviation segments, making Longueuil’s output a critical node in the supply chain for regional and business aircraft operators globally.
Hybrid-electric demonstrator also progressing at Longueuil
Alongside the manufacturing investment, Pratt & Whitney Canada disclosed at Farnborough that ground testing of the flight-standard propulsion system for RTX’s hybrid-electric flight demonstrator has begun at the Longueuil test facility. The company plans to install the system on a modified De Havilland Canada Dash 8-100, with the first flight expected in 2027.
The two announcements together position Longueuil as both a near-term production capacity play and a testbed for next-generation propulsion development. For the regional and business aviation supply chain, the factory upgrade is the more immediately consequential news: tighter production throughput and improved precision manufacturing should reduce lead times on engine components at a time when turboprop and business jet backlogs remain extended across the sector.
The Longueuil investment follows other recent moves by Pratt & Whitney Canada to expand production and support capacity. The company did not specify a completion date for the current modernisation programme, meaning delivery of the new automated lines and digital processes will be tracked closely by the operators and MRO providers that depend on component supply from the Quebec facility.
