Frequently asked questions
- Does Lerner Law handle impaired driving charges?
- Yes. Daniel Lerner spent years as one of the lead impaired driving prosecutors for the downtown Toronto courts before founding the firm, and impaired driving remains one of Lerner Law's primary areas of practice.
- I've been charged with assault, can Lerner Law represent me?
- Yes. Lerner Law represents people charged with assault and other crimes of violence, including cases that raise defences such as self-defence, defence of property, or necessity.
- My 13 year old was charged with a crime, does Lerner Law handle youth cases?
- Yes. Lerner Law has specific experience representing 12 and 13 year old offenders in the youth justice system, where the law, procedures, and consequences differ from adult court.
- Can Lerner Law help with a bail hearing, and what if the proposed surety has a low income?
- Yes. Daniel Lerner previously served as one of the main bail Crown prosecutors in downtown Toronto and continues to work in bail court as duty counsel and per diem Crown counsel, in addition to representing people at their own bail hearings. On low income sureties specifically, the firm's own bail FAQ notes that a surety with a low income can often still be approved, since courts focus mainly on the relationship between the surety and the person in custody and on whether the promised amount is enough to act as a deterrent.

- Lerner Law offers a free initial consultation and works on either a block fee, covering the agreed scope of work, or an hourly rate for more unusual cases. The firm accepts Legal Aid Ontario certificates and has reduced fee options for low income clients who do not qualify for legal aid.

- Daniel Lerner founded Lerner Law Professional Corporation in 2014 after returning to private practice from the Crown's office. It is a solo criminal defence firm based in Toronto, serving clients across the Greater Toronto Area.
