Elsie was a professional engineer in every sense of the title. In addition to practicing her profession she took an active role in various professional engineering organizations. Of all her commitments, the Engineering Institute of Canada (EIC) received the bulk of her attention and participation.
She was their first woman member. As a result, there was some concern and confusion as to how to welcome her into the organization before she left Montreal, Quebec for Fort William, Ontario to work at Canadian Car and Foundry.
Once she arrived in Fort William, she played prominent roles within the organization, and continued to do so throughout her life.
