Almost 50 years of the Canadian Pain Society

A multidisciplinary approach to pain in Canada.

The Canadian Pain Society connects healthcare professionals, scientists, researchers, policymakers, and people with lived experience through evidence-based education.  Our purpose is to drive innovation through advancement and advocacy and revolutionize access and care for those living with pain.

What We Value

Through education and connection, we work to bridge gaps between organizations and individuals across Canada to share insights and resources about chronic pain management. The Canadian Pain Society works with healthcare providers, researchers, policymakers, and other stakeholders to ensure that Canadians living with pain have access to quality care and support.



Leveraging the power of national understanding, relationships, and education to deliver exceptional management and tools to those who live in pain.



Hearing diverse perspectives fuels innovation, deepens connections between people, and drives growth as an organization. 



The foundation that helps us nurture and develop cutting-edge modalities in pain research and management.



Upholding integrity in science through objectivity, accountability, and stewardship.  We further the academic study of evidence-based abstracts for professionals and people in pain.



Preserving human dignity, patient equality, and freedom from suffering.  Advocacy for our vulnerable populations is done every time we step into our professional role.



Providing the opportunity to create mentor-mentee relationships that foster personal and professional development.

Our History

The Canadian Pain Society/Société Canadienne de la Douleur (a chapter of the International Association for the Study of Painhas been a leader in pain research, education, and advocacy since our inauguration in 1974.  

It's a feature of the almost 50-year history that the Society has retained the Chapter’s core belief of fostering an all-inclusive national network of multi-disciplinary members.  Championed by a history of distinguished presidents from a wealth of disciplines, we continually cultivate our contributions to evidence-based education in the face of ongoing voids in health care.

Awards and Grants Committee

Dr. Anna Taylor


A Canada Research Chair in Pain and Addiction and an assistant professor in the Department of Pharmacology. She completed her doctoral degree at the McGill Pain Center in 2011, followed by postdoctoral training at the University of California, Los Angeles in the NIH-funded Opioid Research Center. Her expertise spans the fields of opioid addiction and chronic pain. Dr. Taylor’s research program engages a broad range of disciplines including pharmacology, microbiology, genetics, and animal behaviour to provide mechanistic insight into how affective circuitry contributes to pain and addiction. Her research strives to understand how chronic pain changes affective brain circuits and whether these changes alter the effects of opioids. She explores strategies to improve opioid efficacy while minimizing addiction risk. Finally, she is developing novel, non-addicting opioid agonists to treat pain without abuse liability. This research comes at a critical juncture when safe and effective chronic pain management is increasingly challenging amidst the opioid overdose epidemic. Dr. Taylor’s research has been continuously funded by the National Institutes for Health, the American Pain Society, the Natural Sciences and Engineering Research Council of Canada, the Canadian Pain Society, and the Canada Foundation for Innovation.
