[citation needed] The genesis of Corpac Canada was in the early 1970s with Gord Peariso establishing Peariso Aviation, as an aircraft maintenance and parts supplier.
His first-class maintenance facility serviced over 30 major oil companies operating their own aircraft in western Canada.
In the mid-1980s Peariso Aviation acquired Corpac Canada Ltd., which represented the Piper Aircraft Corporation and sold the Piper Cheyenne turboprop aircraft across Canada.
Over the course of the next 10 years, Corporate Express Business and Charter Airline at times included several scheduled shuttle routes and charters, as determined by customer demand for these services.
Corporate Express operated a scheduled air service between Calgary and Fort McMurray, Alberta.
