Continuing Review / Renewal

Studies are granted Research Ethics Board (REB) approval for a maximum of one year and must be renewed in order to continue. To extend REB approval for a further one year period, a continuing review request must be submitted to the research ethics office.  It is the responsibility of the principal investigator to ensure that a complete continuing review form is submitted to the REB prior to the study expiration date.

Please follow these instructions to request a continuing review or renewal for a study:

Submit completed continuing review form

For eREB studies and migrated pre-eREB studies:

  1. Log into the Unity Health eREB to complete and submit a renewal. For information on creating an account and logging in, please see the eREB page. Guides on completing post-approval submissions can be found in the eREB.

For studies that are not yet migrated:

  1. Complete a continuing review form, with an original signature of the Unity Health Lead Applicant. In lieu of an original signature, the submission email can be sent by the PI or by a research team member with the PI cc’d.

  • Continuing review forms should be submitted prior to the study expiry date, but no earlier than 60 days before expiry.
