Recently launched on February 23rd is a new online database created as part of a SSHRC-funded collaborative project by a team of researchers and front-line organisations across Ontario and Canada, and built in part by Catherine Stinson's Ethics and Technology Lab at Queen's University. Tracking (In)Justice has been created to monitor and provide information about the date and location of police violence as well as age, race, and gender of victims when available based on publicly available sources.
You can view Tracking (In)Justice's information at their website.
The University of Toronto's Faculty of Social Work has an article on the project.
