What Lerners does
Lerners LLP is a full-service Ontario law firm founded in 1929 by Mayer Lerner in London, Ontario, where its headquarters remain. The firm operates from four Ontario locations — London, Toronto, Kitchener-Waterloo, and Strathroy — with 140+ lawyers and 300+ professional support staff, totaling roughly 440 personnel. It serves a horizontal mix of individual clients, business and corporate clients across manufacturing, transportation, technology, healthcare, real estate, and financial services, as well as insurance industry and public-sector entities, across 25+ practice areas including business law, civil litigation, family law, personal injury, wills/trusts/estates, employment and labour, real estate, intellectual property and technology, privacy and cybersecurity, and specialty risk and insurance.
The firm operates as a traditional professional services partnership with no proprietary technology products. Client-facing digital infrastructure is limited to online invoice and retainer payment portals hosted at payments.lerners.ca, supported by accessibility accommodations such as TTY relay, large-print documents, PDF-to-voice, and sign-language interpretation. There are no APIs, mobile applications, AI/ML systems, or technology integrations disclosed. Differentiated capabilities are anchored in long-tenured senior counsel (multiple partners recognized by Chambers Partners, Lexpert, and Best Lawyers in Canada, with lead-counsel appearances before the Ontario Court of Appeal and Supreme Court of Canada), and 95+ years of brand equity in the Ontario market.
Lerners generates revenue primarily through traditional hourly and fixed-fee billing across most practice areas, supplemented by contingency fee arrangements (a standard 33% rate) for personal injury and disability claims. Distribution is direct-to-client through its four Ontario offices, with marketing driven by thought-leadership content (Insights/Blog), earned media (Globe and Mail citations), and community involvement (40+ supported charities and organizations). The firm is privately held as a limited liability partnership with no parent company, no external investors, and no public listing.
