About Anthony De Marco

Clients rate this firm highly on Google.

Anthony De Marco is a Toronto criminal defence lawyer who has practised law since being called to the Ontario bar in 1985. De Marco graduated from Osgoode Hall Law School in 1983 and completed the school's Intensive Program in Criminal Law that same year, working through both prosecution and defence sides of a case as part of the program. Every year since the bar call has gone to criminal defence work exclusively, nothing else.

De Marco is a partner at Monaco Boiani De Marco, Barristers and Solicitors, based on St. Clair Avenue West in Toronto, and represents clients across the Greater Toronto Area, including the York, Halton, Peel and Durham regions, appearing regularly in courts in Toronto, Etobicoke, North York, Scarborough, Mississauga/Brampton and Newmarket. The practice covers the full range of criminal charges, from theft and drug offences to homicide, and De Marco is admitted to Legal Aid Ontario's Extremely Serious Criminal Matters panel, which lets a lawyer represent Legal Aid clients in the most serious cases, including murder, guns and gangs cases. Clients get a free 30 minute consultation, and De Marco takes on qualifying Rowbotham Order applications pro bono, without charge.

The neighbourhood

The office sits at 1205 St. Clair Avenue West, at Dufferin Street, just west of Corso Italia, the stretch of St. Clair Ave W that runs from around Westmount Avenue to Lansdowne and is known as Toronto's second Italian commercial strip after College Street's Little Italy. It's a corridor of cafes, bakeries and independent shops, not a legal district. De Marco's caseload doesn't stay local either: the practice regularly appears in Ontario Court of Justice and Superior Court of Justice locations in Toronto, Etobicoke, North York, Scarborough, Mississauga/Brampton and Newmarket, so the St. Clair office works as a home base for a practice that covers the whole Greater Toronto Area rather than one neighbourhood.
