There have been 3 main aviation companies in Canada as far as I can tell. Bombardier Aerosace, De Havilland Canada and Canadair. De Havilland Canada created the DHC 6,7 and 8 series but De Havilland Canada where bought by bombardier so they are now made under bombardier but are still reffered to as DHC-8-Q400, DHC-6-700 etc. Canadair began production of the regional jet series and they to where bought by Bombardier Aerosace and are manufactures by them but like De Havilland Canada they are still produced under there old name CRJ-1000 (Canadair Regional Jet - 1000)

Canada's first jet fighter was the De Havilland 100 Vampire, in 1948.

De Havilland was created in 1920.

De Havilland ended in 1964.
