John has been the chairperson of Lesperance Mendes’ construction defect practice group since the inception of the firm.

He has also been involved in construction disputes arising out of pre-contractual representations, extra work, changed site conditions and schedule delays, and claims under various forms of construction bonds and insurance.

John has advised strata corporations and owners on a wide range of governance issues as part of his condominium law practice. These include allocating common expenses and special levies between sections and types of strata lots, resolving owner deadlocks through the appointment of administrators or granting of injunctive relief and enforcing bylaws. In addition, he has represented strata corporations in disputes with contractors and service providers.

John’s litigation practice also includes appeal proceedings, class actions, claims against municipalities and defamation claims.
