The mission of the Brain Injury Society of Toronto is to enhance the quality of life for people in the City of Toronto, living with the effects of acquired brain injury through education, awareness, support and advocacy.

BIST was established in 2004 by a steering committee made up of stakeholders - including people with ABI, family members and people who work in ABI support and rehabilitation in collaboration with the Ontario Brain Injury Association. Today, BIST operates under the direction of a volunteer board of directors.

BIST is a grassroots, member driven organization.
