About H. David Locke & Associates
H. David Locke & Associates is a Toronto law firm that practises exclusively in criminal defence. Its site describes its three lawyers, H. David Locke, Paula V. Locke, and Glen Henderson, as trial lawyers who represent people charged with Criminal Code offences from the point of initial police investigation through trial and, if necessary, appeal. It's a small practice: the stated areas of work include impaired driving cases such as "over 80" and refusal charges, domestic offences, sexual offences, drug offences, fraud over $5,000, bail hearings and reviews, and regulatory offences under the Highway Traffic Act and the Compulsory Automobile Insurance Act.
The firm's own published case list cites reported decisions running from 1989 through 2023, across the Ontario Court of Justice, the Superior Court of Justice, and the Ontario Court of Appeal. That range reflects both trial and appellate work in criminal matters over several decades. The office is at 37 Prince Arthur Avenue, Suite 200, in Toronto's Annex neighbourhood.
Practice areas
The neighbourhood
The office sits at 37 Prince Arthur Avenue, on a street the City's East Annex Heritage Conservation District Study recommended for inclusion in its Prince Arthur precinct. The study notes that Prince Arthur Avenue takes its name from Prince Arthur, Duke of Connaught, who served as Governor General of Canada from 1911 to 1916, and that the street name first appeared on a registered plan in 1870. It describes Prince Arthur as the most spacious and open street in the proposed district, with generous lots, setbacks, and mature tree cover, and notes the street's identity for its art galleries and restaurants.
