Before Pro Bono Ontario launched in 2001, there was no tradition of organized pro bono in this province. Yet, lawyers have always responded to our calls in droves whenever we asked them to address the unmet legal needs of vulnerable groups. They did so when we created a program to protect the education rights of school children in 2002, when we launched Canada’s first court-based self-help program for unrepresented litigants in 2007, when we created Canada’s first medical-legal partnership in 2009, and in 2016, when we launched the first province-wide Corporate Pro Bono Summary Advice clinic. Together with our volunteers, we have changed Ontario in terms of who can now access legal assistance, where people can get help, and how the legal profession engages with pro bono.
