About Law Office of Terry Corsianos

Terry Corsianos runs a solo civil litigation practice in Richmond Hill, Ontario, and it's not limited to the immediate area: the firm serves clients across the province. Terry Corsianos was called to the Ontario Bar in 2001 and has since built a practice centered on civil and commercial litigation, corporate and commercial law, and real estate. The litigation work spans the Ontario Superior Court of Justice, the Court of Appeal for Ontario, and the Supreme Court of Canada, covering everything from complex commercial disputes to more straightforward debt collection matters. On the corporate and commercial side, the firm handles unanimous shareholder agreements, licensing and distributorship agreements, shareholder disputes, and general corporate matters, and the real estate practice covers commercial leasing and landlord and tenant disputes.

Terry Corsianos holds a B.Sc. in psychology and criminology from the University of Toronto, an M.Sc.Ed. in counseling psychology from St. Bonaventure University, and an LL.B. from the University of New Brunswick, and offers services in both English and Greek. The firm also publishes legal commentary on notable Ontario decisions. A piece published May 25, 2022 walked through the Court of Appeal for Ontario's ruling in Ernst & Young Inc. v. Aquino, 2022 ONCA 202, which reframed the common law doctrine of corporate attribution in a bankruptcy context.
