About Iris

Iris' practice includes complex commercial litigation, internal and government investigations and white-collar matters, constitutional and other public and administrative law cases, competition matters (investigations, litigation and class actions), and regulatory matters.

Iris is a leading media & defamation lawyer, with related experience litigating privacy and access to information matters. Canadian and international media organizations frequently rely on Iris's expertise in free expression and court openness matters, including defending libel claims, opposing publication bans and getting access to court documents. More generally, she specializes in cases in which online speech intersects with commercial, privacy or other interests. She also regularly deals with evolving laws around social media, technology, and online information.

Iris represents multinational clients on government and internal investigations, including in fraud, anti-corruption and Competition Act matters, as well as in matters involving public-sector laws, such as conflict of interest, lobbying and elections finance legislation. She also advises clients in a range of industries on domestic and international anti-corruption legislation and related compliance programs, and assists with anti-corruption due diligence for commercial transactions.  

Iris has appeared as counsel at all levels of courts in Ontario, the Supreme Court of Canada and the Federal Court of Canada, as well as before administrative tribunals, arbitration panels and inquests.

Iris is the co-Practice Group Leader of the Toronto Litigation & Dispute Resolution group and leads the Blakes Media & Defamation practice. She is also the co-leader of the Firm's Public Sector Crisis & Compliance group, which helps clients navigate high-stakes legal issues where business meets government. In 2021, she was recognized as a Lexpert Rising Star, one of Canada's leading lawyers under 40.
