David Wagner

David, a partner at Wagner Sidlofsky LLP, has substantial experience in both commercial and estate litigation and their nuanced interplay and complexities.

In the last decade, he frequently appeared in court representing clients in high stakes litigation. For commercial matters this often involved shareholder disputes, oppression remedies, contractual disputes and torts. In the context of estates, David’s trials, applications and motions routinely involved many aspects of estate and fiduciary disputes including will challenges, executor removal applications, accounting disputes as well as challenges involving powers of attorney and guardianship applications.

As a mediator, David focuses on estate litigation and guardianship disputes. He takes a practical and nuanced approach to try and help the parties focus on the real obstacles impeding resolution.

David is a respected speaker and writer at CPD programs as evident by the recent Alberta Court of Appeal’s reference to his article dealing with the majority rule clause in the Brodylo Estate (Re), 2023 ABCA 314 (CanLII). He regularly speaks at the Law Society of Ontario’s Trust and Estate Summit, OsgoodePD’s certificate program for Estate Litigation, the Ontario Tax Conference hosted by the Canadian Tax Foundation, the Canadian Bar Association, and the Ontario Bar Association.
