Ontario Cancer Research Ethics Board


Innovative. Collaborative. Progressive.

The Ontario Cancer Research Ethics Board (OCREB) has radically changed the research ethics environment in Ontario for multi-centre cancer trials. Since January 2004, OCREB has been working with researchers, institutions and sponsors to safeguard the rights and welfare of research participants in Ontario while advancing ethically sound cancer research.

OCREB is an expert central oncology REB serving almost every hospital in Ontario that conducts cancer clinical trials. OCREB’s centralized model means that once a study has been approved by OCREB, participating study sites can receive OCREB approval within days. This streamlines the review process, minimizes redundancy, ensures harmonization and consistency, and saves the time and cost of having the study reviewed by an REB at every participating institution (study site).


OCREB is qualified under the Clinical Trials Ontario REB Qualification Program
