The Canadian Vickers Vigil was a single-seat patrol aircraft designed to meet a Royal Canadian Air Force requirement for a forest fire patrol aircraft. In 1926 the RCAF issued specifications for an aircraft to replace the Airco DH.4 aircraft used at the time. Canadian Vickers designed the Vigil which had steel wings, aluminum skin, and was a strut-braced sesquiplane. The aircraft was overweight, which impacted the aircraft service ceiling and performance, which in turn made it unsuitable for its role. Only one was ever built.
