Testing
A prototype, G-CYZJ, was constructed, after which the RCAF evinced an interest in the type as a communications aircraft. Service testing indicated that the aircraft was underpowered and the Armstrong Siddeley Lynx was replaced with a Wright Whirlwind of greater power (220 hp).
In September 1927, the still experimental Vickers Vanessa was used for series of trial airmail runs involving the first airmail delivery. While waiting off the dock at Rimouski, Quebec, on 9 September 1927, RCAF Squadron Leader John H. Tudhope received 502 pounds of mail from the inbound RMS Empress of France While taxiing the Vanessa for takeoff, a strut ruptured and punctured the aircraft's starboard float causing it to tip over to that side. The propeller lopped off half the float and the machine broke up, resulting in the aircraft sinking. Fortunately, Tudhope scrambled to safety and the mail was rescued, eventually reaching its destinations by rail.
Following a subsequent salvage, the Vanessa was considered uneconomical to repair and was abandoned.
Despite a very brief career, the Vanessa has the distinction of being one of the first enclosed cabin aircraft to be designed and built in Canada and the first aircraft to be used in an experimental airmail flight in Canada.
