3. Ethics Review

  • Delegated review for minimal risk studies
  • Full board review for greater than minimal risk studies

4. Revisions (if needed)

Researcher responds to REB feedback, via Reviewer Notes).

5. Approval

Notification of approval is sent via ARISE; research may begin.

REB Turnaround Standards

Review Type Average Turnaround (business days)* Description
Administrative pre-review 5 business days Check for completeness
Delegated review 14- 30 days

Minimal risk studies

Research is considered minimal risk when the probability and magnitude of harm or discomfort are no greater than those encountered in daily life or during routine physical or psychological tests.

Examples:

  • Anonymous or low-sensitivity online surveys
  • Interviews about non-sensitive topics (e.g., work habits, study experiences)
  • Review of de-identified secondary data
  • Observation of public behavior where participants are not identifiable
Full board review 60 days

Greater than minimal risk; requires board meeting

Research is greater than minimal risk when participation could expose individuals to higher-than-everyday risks — physical, psychological, social, or legal — or when it involves vulnerable populations or sensitive topics.

Examples:

  • Clinical trials or interventions involving drugs, devices, or procedures
  • Research involving children, people with diminished capacity, or vulnerable populations
  • Studies about trauma, violence, sexual behaviour, or illegal activities
Amendments & renewals 10–15 days Depends on complexity

Times represent typical averages of time with the REB and may vary depending on submission volume, completeness, and researcher responsiveness.
