De Havilland Aircraft of Canada Limited (DHC) is a Canadian aircraft manufacturer that has produced numerous aircraft models since its inception including the popular Dash 8. The company's primary facilities were located in the Downsview area of Toronto, Ontario for many years; in 2022, it was announced that it would relocate primary manufacturing to De Havilland Field, under development near Calgary, Alberta. The aircraft types currently in production or planned for production include the DHC-6 Twin Otter, DHC-8 Dash 8, and DHC-515 Firefighter.

The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was bought by Boeing in 1986, then by Bombardier in 1992, then by Longview Aviation Capital in 2019; Longview revived the De Havilland Canada brand. Powered by two Pratt & Whitney Canada PW150s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. The Dash 8 was offered in three sizes: the initial Series 100 (1984-2005) and the more powerful Series 200 (1995-2009) with 37-40 seats, the Series 300 (1989-2009) with 50-56 seats, and Series 400 (1999-Present) with 68-90 seats. The QSeries are post-1997 variants fitted with active noise control systems.
