Over the 1923/24 winter the Air Force replaced the Eagle VIII engines with the Eagle IX and the problems caused by lack of power were corrected. Despite its limitations the Viking earned the affections of its crews and for the 1924 season was reported to have proved its air and sea worthiness, to have a wide range of adaptability and usefulness and to have been absolutely reliable. Even the Eagle VIII received and accolade as it was reported that its lack of power was balanced by its sterling dependability. Although the Viking is overshadowed by the Fairchilds and Vedettes it gave excellent service during the pioneer days of the R.C.A.F. and generated an amazing amount of affection among the men who flew and maintained it. In 1928 one detachment of the R.C.A.F. stated that there is no questioning the fact that the Viking has been the most satisfactory type of aircraft used on operations to date.
There was also one civilian Viking IV in Canada. Laurentide Air Services purchased aircraft G-CAEB in June 1922 after which it had an interesting history. Roy Grandy flew the aircraft on a 1400 km flight in 1924 to deliver Treaty Money to aboriginals along the west shore of James Bay, taking several days to complete what had previously required weeks. G-CAEB was also used in 1925 to fly prospectors to various sites in northern British Columbia and Yukon, using Dease Lake as a base, thereby becoming the first aerial mineral exploration in northwest Canada. The aircraft was destroyed in September 1932 when a fuel line broke while airborne. The pilot landed safely in the Strait of Georgia and he and the occupants successfully evacuated the plane.
