Tony advises on all aspects of Canadian competition law, including mergers, criminal/cartel investigations, class actions, advertising and marketing practices and investigations (including price advertising, performance claims and other consumer matters), abuse of dominance and other reviewable practices.

Tony recently re-joined the firm after serving a special appointment as counsel to Canada's Commissioner of Competition from 2014-2016 (Department of Justice Canada).

Tony has also represented clients in matters with multi-jurisdictional and parallel civil and criminal components, including parallel criminal investigations and class action litigation.

Tony has represented parties in a number of Canada’s most significant competition and consumer matters, including the following:

  • Acting for the Commissioner of Competition in the Avis/Budget contested application for deceptive marketing practices before the Competition Tribunal (the first proceeding under the CASL provisions of the Competition Act), including securing a Consent Agreement preventing the respondents from advertising car rentals at prices that are not attainable (i.e., preventing DRIP/partition pricing) and securing a $3 million administrative monetary penalty.
  • Acting for the Commissioner of Competition in the Direct Energy abuse of dominance contested application before the Competition Tribunal, including obtaining an order from the Competition Tribunal preserving the Commissioner’s right to prosecute Direct Energy despite its exit from the relevant market during the proceeding (the first time the Competition Tribunal has made such a finding) and securing a Consent Agreement with a $1 million administrative monetary penalty.
  • Acting for the Commissioner of Competition in all aspects of the Volkswagen/Audi deceptive diesel emission standards investigation and matter.
  • Acting for the Commissioner in numerous complex merger reviews, including Superior Plus Corp./Canexus Corporation, Medtronic/Covidien, Parkland/Pioneer, Acorn Holding/Keurig Green Mountain, Heinz/Kraft; Burger King/Tim Hortons and Alimentation Couche-Tard/Imperial Oil.
