In 1938, the Toronto Harbour Commission began operating a ferry service to the new Toronto Island Airport, then under construction. A scow was adapted for use as a cable ferry, with the intention that this ferry would operate for a five-year period. However, the scow remained in service for 25 years before being replaced by the ferry "Maple City". The backup ferry "Windmill Point" was acquired in 1985 and a new replacement ferry, "TCCA1", in 2006. The Port Authority subsequently purchased another ferry, the "Marilyn Bell 1."
