Sharon Johnston graduated from the University of Toronto in 1966 as a physical and occupational therapist, and subsequently worked in the area of child psychiatry. When the Johnston family moved to Montréal, she completed her master’s and doctorate degrees in rehabilitation science.

When David Johnston became the 28th governor general of Canada on October 1, 2010, he called upon all Canadians to join in the building of a smarter, more caring nation. Alongside his wife, Sharon, Mr. Johnston sought to reinforce learning and innovation, encourage philanthropy and volunteerism, and support families and children.
