About Tsantis Law

Tsantis Law is a sole practice run by Constantine Tsantis, a Barrister and Solicitor, from an office on Elm Street in downtown Toronto, between Bay Street and University Avenue. The firm was established in 1989 and today describes over 25 years of experience across its practice areas. Tsantis works in four main areas: the purchase, sale, leasing, and financing of real estate and owner-managed businesses; domestic contracts and uncontested divorces; estate planning and administration; and civil and quasi-criminal litigation, including commercial disputes, estate litigation, and regulatory infractions.

The firm describes a hands-on approach, communicating with clients in plain English and keeping them informed of developments and options as a matter proceeds. Tsantis Law does not usually take on disputes that fall within the Small Claims Court's monetary jurisdiction (claims up to $35,000), personal injury or workplace accident claims, matrimonial and custody disputes, driving offences and Criminal Code matters, or intellectual property disputes. The practice stays focused instead on the real estate, business, estate, and litigation work described above.
