About Aitken Robertson

Clients rate this firm highly on Google.

Aitken Robertson is a criminal defence firm headquartered in Peterborough, Ontario, with offices and meeting places stretching across the province, from Belleville, Cornwall, and Kingston in the east to Hamilton and London in the west, and up into Newmarket, Brampton, Oshawa, and Toronto in the Greater Toronto Area. Founder Richard Aitken was called to the Ontario bar in 1984, after earning a B.A. in history from Trent University in 1979 and a J.D. from Osgoode Hall Law School at York University in 1982. The practice started small and grew over the following decades into a team; it now includes more than a dozen lawyers alongside paralegals and support staff who work together on client files.

The firm's focus has shifted over time toward impaired driving defence, though it still handles domestic assault, drug charges, and other criminal matters, along with traffic tickets and provincial offences. Aitken Robertson bills using a flat, block-fee method instead of an hourly rate, and it doesn't charge clients for travel time between its offices. The firm owns an Intoxilyzer 8000, the breath-testing instrument used by Ontario police, so its lawyers can examine how the device was operated in a given case. It offers a free 30-minute initial consultation to people across Ontario.

The neighbourhood

Aitken Robertson's head office is on Charlotte Street in downtown Peterborough, one of the city's main commercial streets, which runs toward the Otonabee River at its eastern end. From that base, the firm has built out a network of offices and meeting places rather than staying in one city: Belleville, Cornwall, and Kingston to the east, Hamilton and London to the west, and Newmarket, Brampton, Oshawa, and Toronto in the Greater Toronto Area.

That spread reflects how the practice works day to day. Rather than asking every client to travel to Peterborough, Aitken Robertson's lawyers meet people at offices and meeting places closer to the court handling their case, and the firm doesn't charge for the travel time involved.

Frequently asked questions

Does Aitken Robertson only handle DUI and impaired driving cases?
Impaired driving defence is the firm's main focus, but its lawyers also handle domestic assault, drug charges, other assault and threat charges, theft, fraud, mischief, young offender matters, bail hearings, and criminal appeals, along with traffic tickets and provincial offences.
How much does it cost to hire a lawyer at Aitken Robertson?
The firm uses flat, block-fee billing rather than charging by the hour, so you pay for the work completed rather than time on the clock. It offers payment plans with no interest charged, and accepts cash, cheque, credit card, debit card, money order, or bank draft.
Where can I meet with a lawyer from Aitken Robertson?
The firm's head office is in Peterborough, and it has offices or meeting places in Belleville, Brampton, Cobourg, Cornwall, Hamilton, Kingston, Lindsay, London, Newmarket, Oshawa, and Toronto, plus service areas covering much of the rest of Ontario. It doesn't charge for travel time or mileage between locations.
Can I get a free consultation before I hire a lawyer?
Yes. Aitken Robertson offers a free 30-minute initial consultation to review your situation and discuss possible defences.
I've been charged with impaired driving. Does Aitken Robertson understand the science behind breath testing?
Impaired driving is the area the firm's lawyers concentrate on most. The firm owns an Intoxilyzer 8000, the instrument Ontario police use to test blood alcohol levels, and some of its lawyers have completed Breath Technician training, which lets them examine how the device was used in a specific case.
Does Aitken Robertson handle traffic tickets and other provincial offences?
Yes. The firm's practice covers Provincial Offences Act matters, including traffic tickets such as speeding, stunt driving, and careless driving, as well as driver's licence suspension issues.
