About O'Hara Law

O'Hara Law is a sole practitioner criminal defence firm in London, Ontario, run by Lucas O'Hara. The firm traces its roots to Glen Donald Law, where O'Hara articled after finishing a Juris Doctor at the University of Windsor Faculty of Law in 2013 and an Honours Bachelor of Arts in Criminology at the University of Ottawa in 2010. O'Hara joined Glen Donald Law as an associate and took over the practice in 2018, when the mentor there accepted an appointment as a judge of the Ontario Court of Justice.

O'Hara Law now represents clients charged with a wide range of criminal offences, from assault and drug charges to impaired driving and more serious matters, appearing in the Ontario Court of Justice, the Superior Court of Justice, and the Ontario Court of Appeal. The firm doesn't route files to associates; clients work directly with Lucas O'Hara throughout a case, and most matters are billed on a fixed fee rather than by the hour, with payment plans and legal aid certificates available for clients who qualify.
