Pratt & Whitney Canada (PWC or P&WC) is a Canada-based aircraft engine manufacturer.

[3] During World War II, it assembled Pratt & Whitney Wasp series engines built in the U.S.

[3] In 1963 a total of 41 Sikorsky CH-124 Sea King (originally CHSS-2) helicopters were delivered to the Royal Canadian Navy.

[5] By 2017, PWC was developing a new engine, the Next Generation Regional Turboprop, scalable from 4,500 to 8,000 shp (3,400 to 6,000 kW) for 90-seaters and featuring a new compressor, state-of-the-art propeller and nacelle among technologies, materials and manufacturing processes improvements to deliver 20% better fuel efficiency and 20% less maintenance costs than the PW100.

[7][8] The high-efficiency compressor testing began in 2012 and ran the full range of aerodynamic design points to validate the component efficiency and pressure ratio.
