MAPS Canada’s leadership, staff, and volunteers are dedicated to furthering the scientific understanding and practical application of psychedelic medicine to improve lives.


Our organization is made up of a diverse group of scientists, researchers, students, advocates, and leaders from all sectors. We believe that to solve some of the biggest challenges in human mental health requires people from a diversity of backgrounds, identities, and experiences, who share a common vision: to improve lives through equitable access to legal and regulated psychedelic medicine.
