Abuse of Dominance

PDF version

Abuse of dominance occurs when a dominant firm or a dominant group of firms engages in a practice of anti‑competitive acts, with the result that competition has been, is being or is likely to be prevented or lessened substantially.

When the Competition Act applies

The abuse of dominance provision in the Competition Act may apply when all of the following elements are met:

  • The firm or group of firms has market power, generally defined as the ability to set prices above competitive levels;
  • The firm or group of firms has engaged in or is engaging in a practice of anti‑competitive acts, such as acts that are predatory, exclusionary or disciplinary; and
  • The practice of anti‑competitive acts has prevented or lessened, or is likely to prevent or lessen, competition substantially.

This could happen if, as a result of the practice of anti‑competitive acts:

  • prices are substantially higher; or
  • product quality, choice or innovation are substantially lower.

If the Commissioner believes that all these elements are met, the Commissioner may apply to the Competition Tribunal for a remedial order, including payment of an administrative monetary penalty.
