About AR Law (Arvin Ross Law)

Clients rate this firm highly on Google.

AR Law defends people facing criminal charges, and that's the only kind of law it practises, with impaired driving cases at the front of its work. Arvin Ross started the firm in 2014 and still leads it as founder and lead lawyer, serving clients across Greater Toronto and the regions around it.

Arvin Ross has spent nearly twenty years in the legal field and has handled criminal matters at every level of Ontario's courts. Over those years the firm has worked alongside the lawyers, prosecutors, judges and investigators in its own community, and it's a family-operated practice that knows what a charge can do to a household.

The lawyer is backed by a team. Managing Director Cindy Ross holds two master's degrees, one specializing in law and finance from Queen Mary University of London, brings more than ten years of experience in the financial industry, and runs its finance, compliance, marketing, operations, HR and client service. Kerlan McLean, the firm's paralegal, is a former police officer, and Timoteo Gunning is the intake associate and team lead for operations and client relations.

There are two offices: Unit 119 at 50 Richmond Street East in Oshawa, and 1504 Markham Road in Scarborough, with clients coming from Scarborough, Toronto, Oshawa and the wider GTA. Consultations can happen by phone wherever a client is in the Toronto area, and the first call, about 20 minutes, is free.

Practice areas

Criminal charges of every kind

Criminal defence is all AR Law does, and it takes on any criminal charge, including ones that aren't on its own list of services. The team also helps clients through bail.

Impaired driving and breath samples

Arvin Ross leads the firm's DUI defence, which covers "Over 80" impaired driving charges, refusing a breath sample and cannabis impairment, including challenges to oral fluid screening. Each case starts with a close look at the evidence and how the arrest unfolded, and where a conviction looks likely the firm negotiates with the Crown for lesser charges, smaller fines or no jail.

Other driving offences

Beyond impaired driving, AR Law defends people charged with failing to stop for police, leaving the scene of an accident, dangerous operation of a vehicle and vehicular manslaughter after a fatal crash. It also takes impaired boating charges laid in Scarborough and elsewhere in the GTA.

Assault, domestic and sexual assault

The firm defends assault, domestic assault and sexual assault charges, with strategies sharpened over years of practice. In some cases, self-defence, a breach of the accused's rights or a Crown error may lead to the charges being dismissed.

Fraud, theft, drugs and weapons

AR Law defends people accused of fraud, including clients facing several counts at once. Theft and shoplifting, drug possession and weapons charges are part of the practice too.

Frequently asked questions

I refused a roadside breath test, but I don't think the officer even had a screening device. Can AR Law defend that refusal charge?
AR Law defends refusal charges, and one route is showing the demand itself wasn't lawful. In some of its cases the officer didn't have the approved screening device in hand when the demand was made, which can make the requirement to blow immediately invalid.
I've been charged with impaired boating in Scarborough. Does AR Law handle boating charges?
AR Law defends impaired boating charges in Scarborough and across the GTA. Timing matters, because an early look at what police have disclosed and the evidence that's been kept gives the defence more to work with.
I'm facing several fraud counts. Should I accept the Crown's plea offer before talking to AR Law?
AR Law defends people charged with fraud, including those facing multiple counts who need a thorough defence. The firm's advice is to hold off on any plea agreement until the evidence has been reviewed.
