The Waterloo Wellington Research Ethics Board (WWREB) (formally known as the Tri-Hospital Research Ethics Board - THREB) provides ethical oversight for all research activities that involve human participants, their data and/or biological materials, conducted under the auspices of Cambridge Memorial Hospital, Grand River Hospital and St. Mary's General Hospital. All research conducted within or on behalf of the three institutions must be approved by WWREB before research may begin, with the exception of research reviewed by an alternate Board of Record (e.g. the Ontario Cancer Research Ethics Board).

Conducting Research at one or more of the Institutions:

Prior to the ethics review of a submission by WWREB, all new studies must undergo an administrative review at the hospital(s) where the study will be conducted. Please submit the complete application package to the applicable hospital research representative for administrative review. Once a submission has received administrative approval, it will be forwarded to WWREB.

Please refer to the Submission Checklist for new submission requirements

Each hospital has its own schedule for reviewing new studies. Please consult the applicable hospital research representative for their dates and deadlines.
