About Gardiner Roberts LLP

For over 100 years, Gardiner Roberts has combined the benefits of a full-service law firm with the dexterity of a mid-sized one. Our focused, cross-disciplinary, one-team approach and commitment to understand your business joins our relevant expertise, immediacy and dedication to providing client-centric, hands-on service. 100% Canadian and fully independent, we offer a level of overall efficiency and cost-effectiveness that larger firms can't touch. Resisting "cookie-cutter" law, Gardiner Roberts has built its name - one rewarding client relationship at a time.

Executive Summary

James is a partner at Gardiner Roberts and has been with the firm since he articled here in 2002. As a litigator in the firm’s Dispute Resolution Group, James has experience in a broad range of commercial, real estate and professional liability litigation, including:

  • Professional liability for lawyers (real estate, litigation, family/estate, commercial transactions), financial advisors, accountants, mortgage brokers and real estate agents. 

  • Real estate litigation involving a wide range of closing disputes, title defects, mortgages, easements and adverse possession, title insurance, cottage issues, condominium disputes and Land Titles Act hearings.

  • Commercial contract and business asset disputes, oppression remedies, director/officer liability, shareholder and partnership disputes, privacy issues, receivership liability and various forms of urgent interim relief, including Mareva/civil fraud, employment and non-competition injunctions, and Anton Piller orders.

  • Defamation including Internet-based liability.

James has successfully represented clients as trial and appellate counsel including a claim where the court stated that the allegations could “rock, if not destroy” his client’s career. In another successful trial decision, James persuaded the court to describe his client’s widely distributed business agreement as “iron clad”. James was counsel in one of the only known decisions where an action was stayed by a court at the outset as a result of improper conduct by the opposite party (who hacked into his client’s computer server). Experience is everything.
