The Province of Alberta Government Services flew this Skymaster when it came to Canada in 1978. Sold in 1985, the aircraft was registered to several numbered companies until bought by Hicks & Lawrence Ltd in 1994. Several Skymasters operated fire detection patrols for the Province of Ontario when Hicks & Lawrence were bought by Discovery Air in 2004 (and re-named Discovery Air Fire Services in 2011). After running into financial distress, US based MAG Aerospace bough the fire service in 2017. C-GFSC is registered to Mag Aerospace Canada at the time of uploading.
