About Mary-Margaret

Mary–Margaret McMahon is the current Member of Provincial Parliament for Beaches-East York and the Ontario Liberal Caucus Critic for the Environment and Climate Action.

A natural-born leader, Mary–Margaret was a strong City Builder long before she was elected first to Toronto City Council in 2010 and then to the Ontario Legislature in 2022.

As MPP, Mary–Margaret has been a strong champion for the people of Beaches-East York. A lifelong environmentalist, she has introduced Private Members’ Bills on Emergency Preparedness, Flooding Awareness, Extreme Heat, and the creation of an All Party Climate Change Caucus. Both inside and outside of Queen’s Park, Mary–Margaret is sharply focused on advocating for bold climate policy, improved healthcare, better housing solutions, safer schools, and reliable transportation for her community and all Ontarians.

Mary–Margaret has a knack for bringing people together and inspiring them. Whether it is working across party lines in the Chamber or promoting people power in the community, she ensures everyone’s voices are heard and ideas are valued. With her endless energy and creativity, Mary–Margaret is a true collaborator.
