Free consultationDavid G. Bayliss Professional Corporation is a small criminal defence firm based in downtown Toronto, with a second office in Newmarket. Founder David G. Bayliss earned a B.A. in history from the University of Waterloo in 1979 and a law degree from the University of Toronto in 1982, then articled with criminal defence lawyers Jack Pinkofsky and James Lockyer before being called to the Ontario Bar in 1984. Bayliss later became a partner at Pinkofsky Lockyer, which grew into one of Canada's largest criminal law partnerships, before setting up this practice in 2010. The firm now defends individuals and corporations facing all types of criminal charges, with particular experience in murder, manslaughter, sexual assault, and drug trafficking or possession cases, and a stated focus on Charter of Rights issues.
Much of that career has run alongside wrongful conviction work. Bayliss is a former longtime director of the Association in Defence of the Wrongly Convicted (now Innocence Canada) and a former Toronto director of the Criminal Lawyers Association, and acted with lawyer James Lockyer on the case that led to William Mullins Johnson's exoneration, after 12 years in prison for a murder conviction later overturned. The firm accepts Legal Aid Ontario certificates in certain cases and is a designated member of Legal Aid Ontario's Complex Criminal Case Rate Panel.

Legal aidThe firm's Toronto office sits in Suite 901 at 480 University Ave, on the same stretch of University Avenue that runs past Osgoode Hall to 361 University Avenue, the Ontario Superior Court of Justice courthouse used for the province's criminal and family trials. For a firm built around murder, manslaughter, and other indictable charges, that puts daily work a short walk from the courtroom itself.
The Newmarket office, at 17075 Leslie Street, extends the practice into York Region, where the Ontario Court of Justice runs its own criminal courthouse on Eagle Street West. Having a York Region address lets the firm meet clients and appear on matters north of Toronto without everyone travelling downtown first.
