Ethics Review

Research ethics review is intended to protect human participants and animal subjects by minimizing the harms or risks to which they are exposed during research activities.

What is "research"?

Research means an undertaking intended to extend knowledge through a disciplined inquiry or systematic investigation.  Some knowledge generating activities are not research.  

The Research Ethics Office makes the final determination as to whether or not ethics review is required for a study; if there are any questions about whether or not review is required, please contact REO before commencing your research.

When is ethics review required?

  • Does your project involve collecting input and/or information from people (responses, reactions, measurements, opinions, experiences) or input collected by someone else, including in person, online, in writing, over the phone or by any other means? 
  • Does your project involve the use of human biological materials? Did the sample come from a human body? 
  • Does your project involve using data about people previously collected by someone else (eg. student records, commercial records)? 
  • Does your project involve the collection or use of health information, as defined in the Health Information Act
  • Does your project involve animals? 
  • Are you collaborating with someone who is doing any of the above? 

If Yes to any of the above, call REO.  You may need ethics approval.
