About Aronovitch Macaulay Rollo LLP

Aronovitch Macaulay Rollo LLP, known as AMR LLP, is a Toronto litigation firm with a single office in the city's Financial District. It was established in 1993, though its founding lawyers had already been practicing law since 1982. The firm's name comes from three of its senior lawyers: Walter Aronovitch, called to the Ontario Bar in 1982, Stephen Macaulay, and Don Rollo.

AMR LLP's core practice is insurance defence litigation, and it also handles construction disputes and cyber security and incident response matters. Its lawyers appear before all levels of court in Ontario as well as tribunals such as the License Appeal Tribunal, and some hold certifications as mediators and arbitrators. The firm has represented insurers in claims involving motor vehicle accidents, accident benefits, property losses, and related coverage disputes, work that grew out of the general liability and insurance litigation practice its founding lawyers built starting in 1982.
