He has extensive experience in appellate advocacy, having acted in 16 appeals before the Supreme Court of Canada, as well as cases in the Federal, British Columbia and Ontario Courts of Appeal. He is co-founder of our National Appellate Litigation Group, and was the inaugural editor-in-chief of its award-winning blog, Canadian Appeals Monitor. Eight of his appellate cases have been included in Lexpert Magazine’s annual list of the Top 10 Business Decisions in Canada (2013-2016, 2018), with three ranked #1, and two others have been named a “National Impact Case of the Year” by Benchmark Litigation Canada (2016, 2019). In 2019, he was profiled in Benchmark Litigation Canada as “one of the most promising and active young litigators” in McCarthy Tétrault’s Toronto office.

Brandon frequently acts in judicial reviews and administrative appeals. He delivered the oral argument for Bell Canada and the National Football League on the standard of review in the Supreme Court of Canada’s administrative law trilogy, heard December 4-6, 2018. He has also acted in several other leading administrative law cases, including: Mikisew Cree First Nation v. Canada (Governor General in Council), 2018 SCC 40; Ktunaxa Nation v.

He has significant experience in regulatory litigation involving the communications industry, having appeared in several appeals from the CRTC to the Federal Court of Appeal, along with the judicial review of a Cabinet decision in the Federal Court. He successfully represented Bell Canada in challenging the validity of the CRTC’s Wholesale Code under the Broadcasting Act before the Federal Court of Appeal: Bell Canada v. 7265921 Canada Ltd., 2018 FCA 174.

Bell Canada, 2016 ONSC 7273.

Hrynew, 2014 SCC 71, which established the organizing principle of good faith contractual performance and has been called “among the most important contract law cases in the past 20 years” (The Lawyers Weekly, November, 2014). As well, he successfully represented the respondent in the leading Canadian case on the tort of fraud, Bruno Appliance and Furniture, Inc. v. Hryniak, 2014 SCC 8, and represented the appellant in the landmark summary judgment case of Hryniak v. Mauldin, 2014 SCC 7. He has taught Advanced Contracts at the University of Western Ontario Faculty of Law since 2012, and Economic Torts at the University of Toronto Faculty of Law since 2015.

Wellman, 2019 SCC 19, a class action appeal upholding the enforceability of arbitration clauses in agreements with business customers, and previously served on the executive committee of the Class Actions Section of the Ontario Bar Association.

His class actions often involve cross-border issues, and he recently defeated a proposed $7 billion (USD) secondary market securities class action under Part XXIII.1 of the Ontario Securities Act based on lack of jurisdiction over a foreign issuer before the Ontario Court of Appeal: Yip v. HSBC Holdings plc, 2018 ONCA 626. He also recently struck out the entirety of a proposed class action alleging economic loss from a foreign import ban relating to genetically modified corn: Darmar Farms Inc. v.
