DeFi-ing the Odds: ONCA Upholds Class Action Certification Against Binance


On March 21, 2025, the Ontario Court of Appeal upheld the certification decision in Lochan v. Binance Holdings Limited.1 The class action was brought by Canadian investors who purchased cryptocurrency derivative products from Binance Holdings Limited, Binance Canada Capital Markets Inc., and Binance Canada Holdings Ltd. (collectively, Binance). On the initial certification motion,2 the investors made claims for damages and rescission of their contracts under s. 133 of the Ontario Securities Act (OSA) and at common law, asserting that the cryptocurrency sales were void due to Binance’s failure to register as required under the OSA and for its failure to file a prospectus.

While the outcome of a certification motion is not predictive of the success of the action at the trial of the common issues,3 the Court of Appeal’s dismissal of Binance’s challenge to the certification offers insights into how cryptocurrencies may be addressed through class actions.
