About Lerners LLP

Litigation has been at the core of Lerners LLP for more than 95 years. Many of its lawyers have appeared as lead counsel before the Ontario Court of Appeal and the Supreme Court of Canada, and many are recognized by Chambers Partners, Lexpert and Best Lawyers in Canada. Today it has more than 140 lawyers and upward of 300 support staff across four locations.

Its commercial litigators work with clients in agriculture, banking, construction, healthcare, manufacturing, transportation and a range of other industries, and they act for municipalities and public entities as well.

Lerners has offices in London, Toronto, the Waterloo Region and Strathroy, and each has its own focus. London, where the firm has been for close to a hundred years, has a full team of lawyers on both the courtroom and the transactional side. Toronto is set up purely for litigation, with disputes that run from commercial and insurance matters to health law, professional regulation and appeals, along with personal injury and family cases. In Kitchener, the Waterloo Region team advises startups, scale-ups and tech companies on corporate structure, financing, intellectual property and commercial agreements.

Cynthia Kuehl chairs the firm. Yola S. Ventresca is managing partner of the London office, and Tammy Ring is managing partner in Toronto. Personal injury clients are taken on contingency, which means they pay legal fees only if they receive money through a win or a negotiated settlement.

History

Lerners began in 1929 as a one-person practice. Mayer Lerner opened it, and Sam, Mayer's brother, came aboard a decade later.

On January 1, 2019, Lerners took over the Strathroy law practice of George E. Sinker, which became its Strathroy office.

Practice areas

Injury and survivor claims

Injury clients can find the firm's personal injury practice at its own site, LernersPersonalInjury.ca, and survivors of sexual assault and abuse have a dedicated site too, JusticeForSurvivors.ca.

Family business and unmarried couples

Family clients can draw on the firm's other groups in-house, from counsel on complex family business settlements to estate planning advice. The group also drafts agreements for unmarried couples that set out how assets would be divided, and what parental and financial rights and responsibilities each partner would have, if they break up.

Both sides of class proceedings

Insurance and aviation claims

The firm works for brokers, insurers, captive companies and reinsurers on first-party and third-party insurance products. Its specialty risk group also represents parties in litigation over aviation events, from passenger injury and death to property damage.

Defending health professionals

The health law group defends regulated health professionals across Ontario, from physicians and nurses to pharmacists and optometrists. It appears at inquests, Consent and Capacity Board hearings and appeals, and it gives guidance on newer issues such as artificial intelligence in clinical practice.

Public law and interventions

The firm's public law work includes a CCLA intervention in Bowman v. Ontario (2022 ONCA 477), an appeal over certification of a proposed class proceeding that challenged Ontario's cancellation of the Basic Income Pilot Program. It also advises First Nations and Indigenous peoples, as well as public bodies and private parties, on Aboriginal title, rights and treaty law.

Municipal law

Lerners has acted for Ontario municipalities and public entities for over 40 years. That work has included representing the City of Hamilton in an appeal that upheld its refusal of a proposed transit advertisement, and serving as breach coach to a large library system during a ransomware attack.

Employers and employees

The employment group acts for employees as well as employers, and its lawyers carry out workplace investigations into misconduct and complaints as certified workplace investigators.

Arbitration and appeals

Several of the firm's lawyers hold arbitrator designations and sit as neutral arbitrators in Canadian and international cases, and the firm has represented a car dealership in a dealer agreement termination under the National Automobile Dealer Arbitration Program. At the Supreme Court of Canada, it handles appeals from the leave application through to oral argument.

Dealerships and broadcasting deals

Business law files have included buying and selling automotive dealerships, floorplan financing for dealership lenders and borrowers, and the purchase and consolidation of radio broadcasting businesses.

Homes, development and property tax

Lerners' residential real estate lawyers and clerks handle conveyancing for people buying their first home, selling a family residence or refinancing, from reviewing agreements to title searches and closings. On the commercial side, the firm advises builders, developers, landowners, landlords and lenders, as well as municipalities, on major projects, and it helps clients with property tax reassessments and appeals.

Construction and heritage

In a 2021 Divisional Court case, the firm's construction lawyers won an interim order of prohibition for a community association that kept the Ontario government from tearing down heritage buildings.

The neighbourhood

The London office is at 85 Dufferin Avenue. Around the city, Lerners has helped protect local waterways with LittaTraps and with clean-ups at Harris Park and along the Thames River.

In the Waterloo Region, Lerners works from 305 King Street West, Suite 301, in downtown Kitchener. Besides the startup and tech work, the Kitchener-Waterloo team also practises personal injury and family law.

The Strathroy office, at 53 Front Street West, sits in the heart of town, so local clients can meet with the firm without travelling far.

Strathroy is 35 kilometres west of London. It was incorporated as a village in 1860 and became a town in 1872, and agriculture and food processing are among its major industries.

In Toronto, the office is at 225 King Street West, Suite 1600.

Frequently asked questions

How does Lerners' 33% contingency fee for personal injury claims work?
The standard contingency fee for personal injury work is 33%, and that's the most Lerners will ever charge in legal fees. In most cases, defendants contribute to the client's legal costs, which brings down the fees the client pays. Class actions under the Class Proceedings Act may use different contingency fee arrangements. (Fees as of October 2026.)
Can Lerners help with a surrogacy or egg donation agreement?
Yes. The family law group advises couples on the legal side of assisted reproduction, covering surrogacy, egg and sperm donation and embryo adoption, along with the rights of parents and surrogates.
Does Lerners serve as Independent Legal Counsel to regulators' discipline and fitness to practise committees?
Yes. Lerners lawyers act as Independent Legal Counsel to Discipline and Fitness to Practise Committees, and the firm has represented both regulators and their members in all kinds of regulatory proceedings.
Our municipality doesn't have an in-house lawyer. Can Lerners act as its general counsel?
Yes. Lerners can act as general counsel for a municipality with no in-house lawyer, or pick up overflow work when legal or clerks departments need extra hands. In that role, it can work alongside senior leadership and get to know the municipality's operations and institutional policies.
Is Lerners registered in the federal Controlled Goods Program?
Yes. Lerners is registered in the Government of Canada's Controlled Goods Program, so it can lawfully handle, hold or move controlled goods and technology within Canada.
Does Lerners work with farms and agribusinesses?
Yes. Agriculture clients range from family farms and co-operatives to multinational agribusinesses, startups and public institutions. In one matter, Lerners advised on buying a multi-generational, family-run dairy farm in southwestern Ontario, which involved negotiating the asset purchase agreements, checking the supply management quotas and moving the environmental compliance approvals to the buyer.
