Quebec based Wheeler Airlines was the first to operate this Otter 1956 - circa 1970. Geophysical instrument company Scintrex Limited (an acronym for Scientific Instruments, Research and Exploration) used the aircraft to develop electromagnetic systems for mineral exploration and conduct airborne surveys for notable base metals and uranium exploration. Returned to passenger configuration in 1977, it flew in Quebec with eight airlines until sold to Harbour Air in Vancouver in 2001. With a Vazar turbine conversion the same year, the aircraft is current with Harbour Air at the time of uploading.
