All research at St. Mary's undergoes rigorous ethical review from an external body to ensure the dignity, rights, and welfare of research participants is upheld. All clinical trials are reviewed by Clinical Trials Ontario (CTO). All other studies are reviewed by the Tri-Hospital Research Ethics Board (THREB).

Clinical Trials Ontario
CTO provides ethics review for multi-site research programs across Ontario. CTO reviews all clinical trials at St. Mary's.

Visit the CTO website for more information.

Tri-Hospital Research Ethics Board
The THREB is a shared research ethics board serving St. Mary’s General Hospital, Cambridge Memorial Hospital and Grand River Hospital. THREB reviews all research involving human subjects at these hospitals, except for research reviewed by an alternate Research Ethics Board of Record for one of the hospitals (e.g. the Ontario Cancer Research Ethics Board).
