Competent and Confident Representation

Jason Squire is a partner in Lerners’ Toronto office, with more than 20 years of legal experience. His practice focuses exclusively on litigation and dispute resolution, including arbitration. Jason has extensive trial and appellate experience at all levels of the Ontario courts and has acted in numerous arbitrations.

As a commercial litigator, Jason provides representation in disputes relating to contracts, shareholder rights (closely or publicly held),

employment matters, insolvency disputes, professional negligence and class actions (defence and plaintiff). He has extensive experience with arbitrations, applications, complex motions, and appeals.

Jason believes that lawyers with extensive trial experience are best equipped to succeed in alternative dispute resolution efforts, including mediations and negotiations. “Competence is a given,” he says. “Confidence is the intangible I

bring to the relationship, and that's something our clients pick up on pretty quickly.”

A skilled advocate and quick learner, Jason commits to a deep understanding of the client’s situation, including the dynamics of their business or the industry they work in. He believes that his ultimate responsibility is an exercise in translation and advocacy, arguing his client’s case to a judge or arbitrator in the most compelling way possible.
