In Toronto, mobility is not experienced equally. While some neighbourhoods benefit from pedestrian-friendly streets, marginalized communities often struggle with limited access to safe, efficient, and affordable resources. This disparity impacts everything from job opportunities to healthcare access, reinforcing systemic inequalities in race, class, and ability. Better Streets Toronto (BSTO) is a project that reimagines how digital platforms can advocate for mobility justice through design. Our goal was to bridge this gap to empower communities with the tools they need to advocate for safer streets, better transit, and more walkable neighbourhoods.
