Pratt & Whitney Canada, an RTX company, will invest C$275 million (equivalent to about $195 million) to modernize its largest manufacturing facility in Longueuil, Quebec, as the engine maker prepares to meet growing demand across regional, business and general aviation.
The project will add new automated production lines, upgraded machinery and digital manufacturing processes to the company’s global headquarters near Montreal.
Nearly 4,500 employees work at the 1.23-million-square-foot site, which manufactures components for Pratt & Whitney Canada’s engine families and supports engines used on regional aircraft, business jets, turboprops and helicopters.
“This strategic investment in Longueuil strengthens our industrial capacity, enabling us to better support our customers and meet growing global demand,” Pratt & Whitney Canada President Satheeshkumar Kumarasingam said.
The Canadian government will contribute up to C$34 million through its Strategic Response Fund. Ottawa said the project will maintain 650 jobs and strengthen Canada’s aerospace manufacturing base.
The Quebec government will provide an additional C$9.9 million to support the modernization project, and Pratt & Whitney Canada will fund the remainder of the investment.
The company said the new equipment and production processes will improve manufacturing efficiency and precision. It did not provide a timetable for completing the upgrades or specify which engine programs will receive the additional capacity.
Longueuil serves as Pratt & Whitney Canada’s principal manufacturing center and produces parts used across the company’s portfolio.
That lineup includes the PT6 family, which powers a wide range of turboprops, helicopters and business aircraft, as well as the PW100 and PW150 regional turboprop engine families and the PW300 and PW500 business jet engines.
Pratt & Whitney Canada supports a fleet of nearly 75,000 engines operated by about 14,000 customers worldwide.
The manufacturer announced the Longueuil investment during the Farnborough International Airshow on July 21, 2026.
The company also announced at Farnborough that it had begun ground testing the flight-standard propulsion system for RTX’s hybrid-electric flight demonstrator at its Longueuil test facility.
Pratt & Whitney Canada plans to install the system on a modified De Havilland Canada Dash 8-100, with the first flight expected in 2027.
The Longueuil investment follows other recent moves by Pratt & Whitney Canada to expand production and support capacity as demand for turboprop and business aircraft engines remains strong.
Kumarasingam said the project reinforces the company’s role in Quebec’s aerospace industry while improving its ability to supply customers around the world.
