Behind every case at Dominion Criminal Defence is a small team that knows your name, knows your file, and picks up the phone when you call. We’re a boutique criminal defence firm in downtown London, Ontario, built on a simple idea: advocacy over profit.
Whether you’re facing a DUI or impaired driving charge, an assault or domestic assault charge, a sexual offence allegation, or your child has been charged under youth criminal law, you’ll work directly with a lawyer — not a call centre. Our urgent line is answered 24/7 at (226) 984-7637, and your first consultation is always free.

Dominion Criminal Defence is a boutique criminal defence firm in London, Ontario, founded by lawyer Phillip P. Dinis and licensed paralegal Dallas Thompson. The firm practices criminal law exclusively and represents clients across London, Kitchener, Brantford, Guelph, Woodstock, and Cambridge, with lawyers who have appeared at every level of court in Ontario, including the Court of Appeal.
Phillip’s path to criminal defence started on the other side of the system. After finishing at the top of his Police Foundations class, he spent years preparing for a career in law enforcement — volunteering as an Auxiliary Constable with the Middlesex OPP, campaigning in provincial politics, working with the Canadian Auto Workers’ human rights division, and teaching International Humanitarian Law for the Canadian Red Cross.
That work brought him face to face with the struggles of marginalized people and communities — and it changed his direction entirely. Phillip earned an Honours degree in Political Science and Government Policy at Western University, a Master’s at the University of Waterloo, and Canadian and American law degrees at the University of Windsor and the University of Detroit Mercy, where he spent two years in the Veterans’ Law Clinic helping struggling veterans resolve their legal problems.
He articled under distinguished criminal defence lawyer Alan Gold, one of Canada’s most respected names in the field, before moving home to London to be closer to his son. In opening Dominion Criminal Defence with his longtime paralegal Dallas Thompson, Phillip finally got to practice law on his own terms — putting advocacy over profit.
Christina has practiced criminal law exclusively since her call to the Ontario Bar, appearing at every level of court in Ontario, including the Court of Appeal. She holds an Honours degree in Criminology and Bioethics from the University of Toronto, a Bachelor of Laws from the University of Sussex in the UK, and her Canadian qualifications from the University of Toronto, Faculty of Law.
Long before her Bay Street articles, Christina was volunteering with the Innocence Project on behalf of the wrongfully convicted and with a legal aid mental-health organization in Brighton, England. That thread runs through everything she does: her cases start from a place of empathy and humanity, with a focus on defending those charged with sexual and domestic offences — and on making sure every client understands each step of the court process and every part of their defence strategy.
Outside the courtroom, Christina spends her time with family, friends, and her two dogs, Paddington and Dexter. She is a member of the Law Society of Ontario and the Criminal Lawyers’ Association.
Dallas co-founded Dominion Criminal Defence alongside Phillip and works on every phase of a client’s file — from first meetings and disclosure review through hearings and trials. Raised in a blue-collar London family, she saw early on how legal trouble can upend the lives of ordinary people, and that experience drives how she treats clients today: with genuine empathy and no strings attached.
Dallas studied Criminology at Carleton University before completing her Paralegal Studies at Westervelt College, where she graduated with Presidential Honours and became licensed in Ontario.
When you retain Dominion, Madison — along with Dallas — is your first point of contact. She reviews everything that comes in on your file, tracks every court date and the reason for it, and handles the financial side of your matter. Don’t be surprised if Madison knows more about your file than you do; that’s her job. She’s currently completing a degree in criminology and policing at Wilfrid Laurier University — and it won’t be long before she’s a barrister herself.
