Diana Stepner

Diana joined Siskinds’ Toronto office as a class actions associate in 2023, after summering and articling with the firm. Her class actions practice is focused on representing plaintiffs in litigation involving complex securities, consumer protection and product liability. These types of actions address harm caused by wrongdoings such as financial misrepresentations, false or misleading advertising, breaches of privacy, or dangerous products, among others.

Prior to law school, Diana summered as an audit intern at Deloitte’s Montreal office and graduated on the Dean’s Honour List from McGill University with a Bachelor of Commerce in Accounting and International Business. She went on to attend McGill’s Faculty of Law, where she received a bilingual education in Civil and Common Law and graduated in the top 15% of her cohort with both her Bachelor of Civil Law (B.C.L.) and Juris Doctor (J.D.) degrees.

Throughout law school, Diana worked as a research assistant for several professors, providing research and writing on topics including constitutional law, systemic discrimination, elder abuse, disability rights and Universal Design, and parliamentary anticorruption oversight. She also won Best Plaintiff Factum in the 2021 Winkler Class Action Moot. Beyond academics, Diana was an outspoken advocate on behalf of fellow students in her elected roles of First Year Class President and Student Representative on Faculty Committee, and as co-founder of the McGill Law Club for People with Disabilities.

Diana proudly identifies as a neurodiverse lawyer with invisible disabilities and encourages more legal professionals living with invisible disabilities – including anxiety, depression, or ADHD, among many others – to embrace their membership within the disability community. Far from a hindrance, people with disabilities often provide a unique perspective, a highly creative thought process, and a heightened ability to empathize with others’ struggles, all of which are beneficial when working with or on behalf of our clients.

Outside of work, Diana enjoys indoor and outdoor gardening, abstract painting, and cuddling with her cats, Carbo and Willie.
