How to report cartels?

If you have information or evidence about possible cartel activities, you must contact the Bureau.

There are several ways to contact the Bureau that are safe and confidential. You can:

  • File a complaint online.
  • Become a whistleblower by calling 1‑800‑348‑5358 and pressing “0” to speak with an Information Officer of the Competition Bureau. The Whistleblowing Initiative protects your identity and guards you against retaliation.
  • If your information relates to federal contracts, please call the Federal Contracting Fraud Tip Line at 1‑844‑365‑1616 or file your tip online. You do not have to provide your name.
  • If you are a current or former cartel participant and you help the Bureau unveil illegal activities, you may be eligible to the Immunity and Leniency Programs under the Competition Act.
