About RBMConsulting

RBMConsulting is a Toronto sole practice run by Rohan B. Mathai, focused on transportation and trade related areas of public and international law. The practice covers marine, rail, and aviation regulatory matters, including enforcement actions, licensing decisions, and government procurement, along with oil spill liability under the ship-source and rail accident compensation funds, and trade matters such as customs tariff classification and rules of origin. Before opening the practice, Mathai worked as in-house counsel for several federal tribunals and compensation funds, including the Transportation Appeal Tribunal of Canada, the Canadian International Trade Tribunal, the Office of the Administrator of the Ship-source Oil Pollution Fund, and the Office of the Administrator of the Fund for Railway Accidents Involving Designated Goods.

Mathai was called to the Bar of Ontario in 2016 and is licensed with the Law Society of Ontario. Legal training includes a J.D. from the University of Melbourne, a Certificate in Transnational Legal Studies from Kings College London, and an LL.M. from the University of Toronto Faculty of Law, plus an earlier B.A.S. in mathematical science and psychology from the University of Guelph. Mathai also teaches asynchronous courses at Memorial University, Marine Law since 2022 and Marine Environment Law and Pollution Control since 2021, work that runs alongside the practice's regulatory focus.

The neighbourhood

RBMConsulting's Toronto address is Suite 600 at 10 King Street East in the city's financial district. The building operates as The Chambers at 10 King East, a shared workspace built for solo and small law practices, with day offices and boardrooms rather than a private storefront suite, and Mathai meets clients there by appointment.

The location sits within walking distance of the underground PATH network, the King streetcar and subway stations, and Union Station, and it's a short walk from St. Lawrence Market. That makes it a practical meeting point for clients travelling in from elsewhere in the GTA or arriving by train, which fits a practice that deals with federal transportation and trade regulators rather than a single local courthouse.
