George Gray, Founder & Principal

George Gray

Founder & Principal · Barrister & Solicitor

George Gray built Gray Defence on a single conviction: that anyone facing the power of the state deserves a defence as relentless and resourceful as the prosecution against them.

Called to the Bar of Ontario in 2009, George has spent more than fifteen years defending the accused — first as a criminal litigator at one of Canada's leading national law firms, and now as the founder of his own practice. He has appeared at all levels of court in Ontario and prepared written advocacy for matters before the Supreme Court of Canada.

His perspective was forged well beyond the local courthouse. George has worked internationally as a delegate advocating for due process and fair treatment on behalf of individuals accused of the gravest offences — war crimes, terrorism, and armed-conflict-related charges — and has contributed to justice initiatives with Lawyers Without Borders (Canada) and the Association in Defence of the Wrongfully Convicted. That experience informs a defence philosophy built on rigour, creativity, and an unflinching willingness to challenge the Crown's case.

George is regularly invited to explain and analyze criminal-law issues in national media, including CBC's The National, and is the creator of The Legal Gray Zone, where he breaks down how Canadian criminal law actually works. He defends clients facing assault, sexual assault, impaired driving, and drug-related charges.

Kinza Siddiqui

Associate · Barrister & Solicitor

Kinza Siddiqui is a criminal defence lawyer whose practice spans the full arc of a case — from the urgency of a bail hearing to the rigour of a trial — and whose path to law was driven by a deep commitment to the rights of the accused.

Called to the Bar of Ontario in 2024, Kinza built her foundation quickly and in serious matters: independently conducting bail proceedings from arrest through hearing, running summary conviction trials on charges including assault, criminal harassment, and break and enter, and serving as second chair on a first-degree murder preliminary hearing. She has also acted as Amicus Curiae and as counsel under sections 486.3 and 672.24 of the Criminal Code, including in mental-health and fitness matters.

Her commitment extends beyond her own cases: her student research on the law of human trafficking was used to help sponsor Bill S-224, a federal bill amending the Criminal Code's definition of exploitation, and she facilitated post-secondary education for incarcerated women through the Walls to Bridges program. She holds a J.D. from the Lincoln Alexander School of Law at Toronto Metropolitan University and an Honours B.A. in Criminology & Socio-legal Studies from the University of Toronto.

A senior advocate on every case. A full team behind it.

When you retain George Gray, your case is led personally by him — he is at the table for the decisions that shape your defence and present in court for the moments that matter. He also leads the firm's associates, staying actively involved in their matters and holding every file Gray Defence takes on to the same standard of preparation and judgment.

We believe a strong defence is built, not improvised. That means understanding your circumstances, mastering the disclosure, identifying every weakness in the Crown's case, and preparing as if every matter is going to trial — because that preparation is what creates leverage, whether your case is resolved early or fought to verdict.

Your future is worth defending.

If you are under investigation or facing criminal charges, the most important step is to get experienced advice early. Consultations are free and confidential.
