City Express (French: Cité Express), also known as Air Atonabee Ltd., was an airline based in Ontario, Canada, from 1971 to 1991, which operated passenger services in eastern Canada and the northeastern United States.
In 1984, Air Atonabee was acquired by Victor Pappalardo and reorganized into City Express. The airline relocated its base to Toronto Island Airport (now Billy Bishop Toronto City Airport) (YTZ) where it began STOL service.
City Express ceased operations in February 1991.[1][3][4]
