Powerful data,
powerful possibilities.

Powered by more than 225,000 volunteers across the province who are sharing health information as they age, the Ontario Health Study (OHS) gives  researchers the large-scale, long-term data they need to identify population-level health patterns and trends. The insights they gain could lead to new strategies for preventing, detecting and treating cancer and chronic disease — and make life better for all Canadians.
