The first new project that Elsie MacGill took on at Canadian Car and Foundry was to design the Maple Leaf II. This training prototype was based on the Maple Leaf project which Elsie studied and then decided to basically redesign. The 'II' was added to the name to clearly distinguish between the two designs.
Elsie's efforts were lauded by her colleagues in the Engineering Institute of Canada as the plane was recognized for its airworthiness and the designer for her efficiency in undertaking the project and completing the work in so timely a fashion.
Unfortunately, as there were already other trainers being employed by the Royal Canadian Air Force the Maple Leaf II did not rise to any prominence in Canada beyond its prototype status.
