About Lyttle McGarry Del Greco LLP

Lyttle McGarry Del Greco LLP is a small Ottawa firm that focuses exclusively on criminal defence, from its office on Lisgar Street in the city's downtown core. The three founding partners, Ewan Lyttle, Brett McGarry, and Biagio Del Greco, each built years of criminal law experience before joining forces. Lyttle articled with the Ottawa Crown Attorney's Office and then spent a decade working alongside criminal defence lawyer Patrick McCann. McGarry clerked for the judges of the Superior Court of Justice in Ottawa after graduating from Dalhousie Law School in 2007 and has practised criminal and regulatory defence since 2008. Del Greco, called to the bar in 2009, is fluently bilingual in French and English and can also represent clients in Italian.

The firm takes on the full range of criminal and quasi-criminal charges, including homicide, sexual assault, drug and firearms trafficking, fraud, and impaired driving, along with regulatory and Indigenous law matters. Its model keeps a single lawyer on a file from start to finish instead of splitting the work across staff. Associate Maggie McCann, who articled at Bayne Sellar Ertel Carter, joined the firm in 2022 and now carries an independent caseload alongside the partners.
