Air Atonabee was acquired by Victor Pappalardo in 1984 and renamed City Express. A pair of DHC Dash 7's (including C-GGXS, ex-4X-AHB) from Arkia Israel Airlines launched commuter service between Toronto Island Airport (YTZ), Ottawa (YOW) and Montreal (YUL). City Express ceased operations in Feb. 1991, but C-GGXS went to Pappalardo's Trans Capital Airlines and later flew for the UN. It was one of seven Trans Capital Dash 7s sold to Air Tindi in March 2021. At least five Dash 7s are still parked at YTZ (2 x Trans Capital & 3 x Air Tindi) near the relocated 1939 airport terminal building.
