Once the work on the Hawker Hurricanes started to wrap up, a new contract was undertaken by Elsie's engineering team and the workers at Canadian Car and Foundry to produce the American Helldivers. This once again required a retooling of the plant, and the work came with many difficulties. In fact, the plane became known as "The Beast". This was not because it was a scary fighter plane, it was scary on the ground as there were so many changes to the blueprints it was hard to get them off the ground!
It was during this contract that Elsie left Canadian Car and Foundry in 1942 and decided to start up her own consulting firm in Toronto, Ontario. It was a contentious time for her and the plant manager E.J. Soulsby.
