Your project is minimal risk if the risk of harm anticipated in the proposed research is not greater, considering probability and magnitude, than that which is ordinarily encountered in daily life or during the performance of routine physical or psychological examinations or tests.
Risks of daily life mean those risks encountered in the daily lives of the participants of the research, considering their actual life situations, as opposed to the daily life of "all persons" or of "healthy volunteers" as the case may be.
If your study is minimal risk, it will be reviewed via delegated review by the Chair or Vice-Chair of the Research Ethics Board (REB).
If your study is above minimal risk, it will be reviewed by the REB at a full board meeting, and will need to be submitted by the appropriate deadlines:
