During the Korean war a Russian pilot desert and fly its apparel behind the Canadian lines. He is granted Canadian citizenship and the plane is brought back to Canada. A Canado-American team disassemble, reassemble and test the plane, the American and Canadian military are satisfied with the combat spec intel and simply shelves the plan. But Avro is able to get its hand on the blueprint and breveted the plane with slight modifications as the Avro Dart. Cheap and effective, the Canadian MiG (as some nickname it) is chosen as interceptor for Canadian airspace. An initial command of 200 is requested but politic get in the way. First is the American military who violently complain about the similarity and risk of confusion, then Russian ambassador asking for royalties due to thievery, the Dart seem to face a bleak future. To settle the problems, the Canadian government reduce the Dart command to 150, then a 100, to finnaly settle at 65, dealing with North American Aviation a liscencing right for the F-86 Sabre as its main air component. The Canadian MiG is restrained as an arctic interceptor, requiring Avro to modify the Dart engine (both for its new purpose and dismiss the Russian complain).
Despite its survival, the budget cut would eventualy force the reduction of the active plane to a mere 25, mothballing the remaining 40 or keeping them as replacement. The Canadian MiG will, however, be greatly appreciated by its pilots, mainly for being reliable and agile even in the worst arctic wind. They will be eventualy almost forgotten, as a cost saving measure, as the CF-104 Starfighter came and go, being replaced themselves with the CF-18, the arctic interceptors will be kept as Avro Dart, with small modifications to adapt to the changing technology.
Their career will however stop in 2001 with the Incremental Modernization Project. The modernized CF-18 replaced the aging Dart as artic interceptor and the new Boeing F-18E Super-Hornet replacing the CF-18 as the main Canadian air componant.
