Trans-Provincial Airlines was acquired by the Pattison Group in the early 1980s when Air BC was formed but operated as a separate division primarily serving the north coast of British Columbia. The main base of operations was the former wartime RCAF seaplane base at Seal Cove in Prince Rupert. Goose CF-EFN operated on the BC coast from the early 1970s until Feb 28, 1991 when it was damaged when it ground looped on landing at Sandspit Airport (CYZP). The wreck was acquired by the Tongass Historical Society in Ketchikan (AK) in 1992 as N88821, and was still under restoration for static display with them by 2022.
