ABOUT SAMUEL KASSIRER

Durham Region criminal defence lawyer 
In your corner from the start

Facing a criminal charge is one of the most stressful experiences of a person's life, and you deserve more than a lawyer who simply goes through the motions. I am a criminal defence lawyer serving Durham Region, and I built my practice believing that every client deserves a defence strategy built specifically for them. I scrutinize the evidence, hold the Crown to its obligations, and ensure the Canadian Charter of Rights and Freedoms is not just a document.

I grew up in Whitby playing hockey and soccer, learning what it meant to be part of a team. During my youth I was surrounded by passionate criminal defence lawyers which sparked my path to the courtroom. 

I attended to Bond University in Australia, where a passion for mooting and live advocacy made the choice clear: I was meant to be on my feet, advocating for people. I strongly believe we are not defined by our worst moments, and whether you are facing charges from Oshawa, Whitby, Ajax, Pickering, or anywhere across Durham Region, I am ready to stand beside you. On your team.

"Every client I meet is going through one of the most stressful and hardest moments of their life. My job is to make sure they don't face it alone."

FREQUENTLY ASKED QUESTIONS
Common questions

What should I do after being charged?

If you have just been charged with a criminal offence or quasi-criminal offence, contact a lawyer. They can provide you with important information, guidance or advice about your next steps.

How quickly can you help with a bail hearing?

Bail hearings can happen fast, on short notice, sometimes within 24 hours of an arrest. A strong and carefully prepared bail plan may be critical to securing release and must be presented to the court. You want to put your best foot forward. Call Samuel now at 905-442-2468 for prompt, professional assistance with bail hearing preparation and representation.

Do you offer payment plans?

Yes. Samuel understands that facing criminal charges is already stressful enough. Fee arrangements are discussed during the initial consultation on a case-by-case basis.

Can a criminal charge be withdrawn or reduced?

Yes. Depending on the facts and circumstances of the case, charges may be withdrawn, diverted, or reduced through discussions with the Crown Attorney. Outcomes are determined on a case-by-case basis, as every case is unique. 

What areas do you serve?

Samuel practises at courts that serve the jurisdictions of the Durham Region (Oshawa, Whitby, Ajax, Pickering, Clarington), Newmarket, Peterborough, Cobourg, Lindsay and Toronto.
