Experience

May started her legal career as a litigator in intellectual property at a full-service firm, expanding her expertise to trademark prosecution and developing a practice focused on brand protection and enforcement.  She has spent over 25 years working for clients across a wide variety of industries, but particularly in retail, travel, fashion and food – all sectors that she happens to especially enjoy.

May’s litigation experience includes patent, trademark and copyright infringement cases, as well as expungement and injunction cases in the federal and provincial courts.  Over the course of her decades-long legal career, she worked at a succession of large Bay Street firms before finding a Bay Street firm that truly reflects her core values of diversity and inclusion, where she can focus on what she loves most: working with forward-thinking and brilliant legal professionals who prioritize having fun and living fulfilling lives while also practicing law and focusing on the best interests of clients.

While enjoying a reputation as a “fearless” advocate, May’s goal is to arrive at the best business solution for her clients, which is often not going to be achieved through protracted litigation.  She prides herself on finding creative solutions to complex problems and having a deeper understanding of the underlying goals from nurturing long term relationships with her clients.
