This 1975 Shrike Commander came to Canada in 1999 for Hicks & Lawrence Limited. Renamed Discovery Air Fire Services in 2011, the parent company Discovery Air sold the fire service division to MAG Aerospace in 2017. Part of an unsuccessful attempt to stave off bankruptcy due to high debt load, Discovery Air went bankrupt in 2018. The aircraft is current with MAG Aerospace at the time of uploading.
