Sheila Ward, a longtime school board trustee, passed away Wednesday evening.
"Sheila was a tireless advocate for her community and public education," the TDSB said in a statement.
A school trustee for more than 20 years, Ward represented Toronto Centre Rosedale since 1997.
"I am glad that others are willing to spend their time looking after potholes, sewers and snow ploughing. Those are essential and important tasks but for me education is where I want to serve my community and I am extremely fortunate that the voters of Toronto Centre Rosedale allow me to continue in a job I love," Ward wrote on her website.
Born in Toronto and educated here and Regina, Ward also worked in the media.
According to her site, her freelance work included being an on-camera public affairs commentator for CBC TV and radio in Saskatchewan, and on the CBC program Marketplace.
The TDSB said that "in the days and weeks ahead, we will be looking at how best to celebrate Sheila's life. The flags at the Board's Education Centres will be lowered to half-staff for the remainder of the week in her memory."
