Maggie Coffin-Prowse joined McInnes Cooper in July 2013, bringing with her a strong independent practice in corporate and commercial law.


With a solid foundation and history in the community of Saint John, Maggie has a strong repertoire with engineers, small business start-ups, contractors, and commercial building owners (among others). After years of private practice, Maggie expanded her corporate commercial cache as in-house counsel for an international oil company and as General Counsel for Jacques Whitford Ltd., an international engineering company. Her clients appreciate her flexibility, practicality, and goal-oriented mind-set. Maggie’s clients and colleagues alike know that if there is any potential for opportunity, she will seize it.


Maggie is passionate about solving problems and bringing two parties from widely oppositional sides together. Her passion for resolution translates into her ability to transcend disagreement and discomfort to make all parties excited for their new respective opportunities. Maggie’s highest compliment is when her clients consider her to be a part of the success of their business. Her ability to connect and create strong working relationships demonstrates to her clients that she really does care.


Prior to her professional career, Maggie obtained her law degree from UNB and then went on to receive her LLM from the University of Alberta. She mentors the Environmental Law Society at the University of New Brunswick, Faculty of Law and is the President of First Steps Housing Project Inc., a local shelter devoted to sheltering pregnant and parenting women who have no safe place to live. She is also the Chair of the Construction Law Section of the CBA.


Maggie will continue her corporate/commercial practice, with a special emphasis on environmental law and construction law issues.
