MAP launched 10 national, collaborative solutions networks with a common goal: to effect real-world social change by co-designing and demonstrating what works to address critical urban health challenges in our communities. On March 2-3 2020, just days before the COVID-19 pandemic was declared, MAP hosted a symposium in Toronto that brought together more than 170 network members from across the country: scientists, community partners, policy makers, and people with lived expertise.
