Feeling that a Gliding Club would be well received by the military, and with the approval of their employers, some staff at the de Havilland Aircraft Company of Canada decided to form their own.
Members of the drawing office worked in their own time to produce the engineering blueprints, de Havilland and other companies took an interest, assisting the project with donations of instruments and a landing wheel.

The wings carried some dihedral and there was washout, a decrease in angle of incidence outwards along the span, on the outer panels to avoid spin initiation at the stall.
