About Lerners

It all started with two brothers and one simple truth.

In 1929, Mayer Lerner opened the doors to his law firm.  Joined by his brother Sam in 1939, they faithfully applied the philosophy that “no matter who our clients are, each and every one deserves the best representation possible.” Today, more than 90 years later, this simple truth is still at the heart of our values.

Four distinct offices… one impressive firm.

Lerners LLP has grown to become one of Ontario’s largest firms with offices in London, Toronto, Strathroy, and Waterloo Region. Lerners has been recognized by peers, colleagues and clients and is listed in Canadian Lawyer Magazine.

The original Lerners office, in London, has always been a full-service shop. The largest of its kind in southwestern Ontario, it offers outstanding skill and vast experience in a variety of practice areas under one roof.

The Toronto office, opened in 1987, focuses on litigation and is now one of the city’s largest litigation boutiques. The Toronto arm of the firm has also been recognized by Canadian Lawyer magazine.

While each office possesses its own unique strengths, we work closely together for the benefit of all our clients. In total, over 130 highly skilled and experienced lawyers, with the help of more than 200 dedicated support staff, share expertise and resources to deliver exceptional client service.

Experience is important, but it’s how you put your experience into practice that really matters.

There is no shortage of experience available today. There are plenty of lawyers who can, quite rightly, describe themselves as being experienced, tough, tenacious and uncompromising.

But if we’ve learned anything in our 90 years of successful client service and representation, it’s that experience will only take you so far towards building trust and rapport with a client. Our fundamental obligation is to first listen and understand. Only after we’ve done that can we apply our experience to your advantage.

Here’s what you can expect if you choose Lerners

We will listen until you are sure we’ve heard you.

Successful outcomes start with a crystal clear definition of what you want to make happen. As part of our learning curve, we will ask questions. Pointed and necessary questions but, in our experience, they will all be the right ones to ask. We will listen until you are convinced we see things through your eyes. Ultimately, it’s what you tell us that will shape a successful resolution.

We will explain all your options until you say you understand them.

Explaining options is one thing. Helping you understand them is quite another and this is an area where we excel. We’re very good at combining our specialized experience with innovative new approaches and strategies to develop a host of viable options and then explaining each of them to you. Only when you are satisfied that you fully understand all your options, will we propose a course of action that we believe is in your best interests.

And we also use information technology to full advantage as a communication tool. It enables us to turn mountains of case-specific data into useable, easily-understood information so you will always know where your case is heading and why.

We will do everything we say we will do.

Trust is an indispensable privilege we earn by keeping our word. This trust is the foundation of the many long-term client relationships we enjoy, and the basis for numerous referrals we receive via clients and/or their trusted advisors. Our readiness to litigate and record of success are well documented. And our clients know we will fiercely and fairly protect their interests all the way to the Supreme Court of Canada if necessary. We don’t get surprised and won’t let you get surprised. You have our word on it.

We will not waste your time or your money.

Whether negotiating your settlement in the boardroom or arguing your case before the highest court in the land, we always know precisely where we are going. Our ability to match skill sets to critical legal issues at every stage means we deploy resources efficiently and effectively. We don’t waste one minute of your time or one penny of your money along the way.
