About The Defence Group

The Defence Group is a solo criminal defence practice founded in 2003 by Arun S. Maini, a barrister and solicitor who has practised criminal law since 1995. Maini is a graduate of the University of Toronto and Dalhousie University Law School. After articling at a Bay Street law firm, Maini joined the federal Department of Justice as a prosecutor of drug trafficking, tax evasion, and immigration fraud cases in Toronto, Brampton, and Vancouver. In 1999, Maini moved to the provincial Crown attorney's office in Brampton, prosecuting offences ranging from theft to murder, before leaving government in 2003 to start the firm.

The firm is based in downtown Toronto, with client convenience offices in Oakville and Vaughan; the firm describes both as there for the convenience of clients in those areas rather than as separate full locations. As a solo practice, Maini personally handles each case, from the initial consultation through negotiation and, if needed, trial, and assembles a defence team, which can include forensic toxicologists, psychologists, or private investigators, based on what a case requires. The practice covers the full range of criminal charges, including domestic assault, sexual assault, drug and weapons offences, driving under the influence, fraud, white collar crime, and murder, with extensive jury trial experience.
