About AR Law (Arvin Ross Law)

Clients rate this firm highly on Google.

AR Law is a small criminal defence firm founded in 2014 by Arvin Ross, a barrister and solicitor with nearly twenty years in the legal field. The practice runs from two offices, one in downtown Oshawa and one on Markham Road in Scarborough, and it serves clients across the Greater Toronto Area along with York, Durham, Peel, and Halton regions. It sticks to one area of law: criminal defence, covering assault, domestic assault, drug possession, DUI (including marijuana related and refusal charges), fraud, theft and shoplifting, weapons charges, and vehicular manslaughter. New clients can start with a free 20 minute phone consultation.

The team is small, five people combining legal work with operations and client service, and it includes a paralegal licensed by the Law Society of Ontario. Managing Director Cindy Ross runs finance, compliance, marketing, operations, human resources, and client service, and holds an MA and an MSc with a specialization in law and finance from Queen Mary University of London. Before joining AR Law, Cindy Ross spent more than a decade in the financial industry and lectured at university in French and finance.

The neighbourhood

The Oshawa office is at 50 Richmond Street East in downtown Oshawa, in a shared office and coworking space called The Firms. The Ontario Court of Justice location that handles Durham Region matters is nearby at 150 Bond Street East, putting the office and the courthouse it deals with in the same downtown core.

The Scarborough office is on Markham Road in Malvern, a northeast Scarborough community built on former farmland starting in the 1970s that's become one of Toronto's most ethnically diverse neighbourhoods, with residents tracing roots to more than 60 different cultures. The office gives the firm a second, local point of contact for clients in that part of the city.
