Pratt & Whitney Canada (PWC or P&WC) is a Canadian aircraft engine manufacturer. PWC's headquarters are in Longueuil, Quebec, just outside Montreal. It is a division of the larger US-based Pratt & Whitney (P&W), itself a business unit of United Technologies. [1] United Technologies has given PWC a world mandate for smaller aircraft engines while P&W's US operations develop and manufacture larger engines.

Although PWC is a division of P&W, it has its own research, development and marketing as well as the manufacturing of its engines. Since the development of its famous PT6 turboprop engine in the 1960s, PWC has dominated its sector of the world market for aircraft engines. The company currently has 10,000 employees worldwide, with 7,000 of them in Canada.



The Canadian Pratt & Whitney Aircraft Company, Ltd. was founded in November 1928 to act as a service centre for P&W aircraft engines.[2] During World War II, it assembled Pratt & Whitney Wasp series engines built in the U.S. In 1952, the production of Wasp engines was transferred to P&WC so P&W could concentrate on developing jet engines.

In the late 1950s, a team of 12 P&WC engineers began the development of the first small turbine engine in Canada, the PT6. The first example was delivered to a customer in 1963.

In 1962, the company was renamed United Aircraft of Canada, and assumed its current name in 1975.[3]
