We encourage whistleblowers and anyone representing a whistleblower to review our Submission guide, Protections and Award eligibility sections of this website prior to contacting our office with any questions.

Whistleblower-only hotline: 1-888-OSC-5553 (1-888-672-5553)

This hotline is for individuals who are considering reporting and have specific questions about making a submission, as well as for people who have already submitted a whistleblower report.

Voicemail messages must include:

  • your full name
  • the subject of your inquiry
  • a phone number where you can be reached
  • dates and times you would be available for a return call
  • your Submission ID (if you have already submitted a report)

We return calls within two business days during regular business hours. To protect your confidentiality, we will not leave a voicemail message unless the voicemail greeting clearly indicates that the phone number belongs to you.

Please note, as set out in our Policy, we will not provide information about the status of a matter to protect the confidentiality and integrity of the reviews and investigations that we conduct.
