The Fox Moth was based on the Tiger Moth and used the Tigers wings, tail assembly, landing gear and engine mounting. To these basics de Haviland added a new plywood covered fuselage enclosing a cabin for four passengers. The pilot was located in an open cockpit behind and above the cabin. The prototype Fox was shipped to Canada for trials with floats and skis carried out by Canadian Airways Ltd. CF-ADI was the first Fox in Canada.
In all, eight of the ninety two Fox Moths built in Britain, were shipped to Canada and it appears that Arthur Fecteau of Senneterre, Quebec bought the first production model.
