Osler has a highly respected team of litigators with extensive experience in all types of contested proceedings under the Competition Act, whether defending against civil action initiated by the Commissioner of Competition or a private party(ies), or criminal prosecutions initiated by the Public Prosecution Service of Canada. With deep bench strength required to efficiently manage complex proceedings before the Competition Tribunal and all levels of courts in Canada, Osler has significant experience in achieving optimal outcomes for our clients.
Without question, competition law enforcement in Canada is on the rise. The Competition Bureau is building its litigation capability and adopting a more aggressive enforcement posture. Equally important, private parties now have an expanded ability and incentives to bring actions under the civil provisions of the Competition Act, creating new strategic risks for businesses.
With heightened litigation risk, businesses need reliable and proven counsel. Our firm has one of the leading litigation practices in the country, and our litigators have been involved in numerous competition-related proceedings in Canada, including virtually every cross-border competition-related class action.
