Canadian competition law is governed by the Competition Act (the Act), which includes criminal provisions, provisions for merger review and civil provisions relating to abuse of dominance. The commissioner of competition (the commissioner) heads the Competition Bureau (the Bureau) and has responsibility for administration and enforcement of the Act. Criminal cartel cases are prosecuted by the director of public prosecutions (the DPP) in the courts. The Competition Tribunal (the Tribunal) can, on application to the commissioner, grant remedial orders in merger and abuse of dominance cases. Guidelines published by the Bureau set out the commissioner’s approach to enforcing the merger, abuse of dominance and cartel provisions.
