About Calvin Barry Professional Corporation

Calvin Barry Professional Corporation is a Toronto criminal defence firm run by Calvin Barry, a lawyer who limits the practice entirely to criminal defence and doesn't take on other areas of law. The firm is based at 113 Front Street East in downtown Toronto and serves clients across the Greater Toronto Area, including Mississauga, Brampton, Vaughan, Scarborough, Oakville and Hamilton. Its work centres on impaired driving and DUI charges, along with domestic assault, sexual assault, drug offences, violent offences and fraud.

Before opening a private defence practice in 2004, Calvin Barry worked as a provincial prosecutor with the Ontario Ministry of the Attorney General starting in 1983, then served as an Assistant and later Senior Crown Attorney from 1988 to 2004, prosecuting matters at all levels of trial court. Barry articled at Gardiner Roberts, a Bay Street law firm, in 1986 and 1987. That prosecutorial background carried into board and committee work with the Ontario Crown Attorney's Association and the Canadian Bar Association's Criminal Law Section, along with lecturing at the Law Society's Bar Admission Course and Osgoode Hall's Trial Advocacy Workshop. The office also keeps two dogs, Buddy and Lola, who greet visitors at 113 Front Street East.

Who handles what

The neighbourhood

The firm's office on Front Street East sits in Toronto's St. Lawrence neighbourhood, close to St. Lawrence Market, a public market that has operated in the area since 1803 and drew a National Geographic food market ranking in 2012. The neighbourhood overlaps with Old Town Toronto, where the original town of York was founded in 1793 on a site just north of Front Street, and where Upper Canada's first parliament buildings stood at Front and Parliament Streets that same year. It is one of the oldest parts of the city, now a mix of converted warehouses, market stalls and office space a short walk from the downtown core.
