EXPERIENCED DEFENCE LAWYERS
When you call us, you retain an experienced criminal lawyer who has a track record of results defending complex criminal matters and stands up for you in court. Whether you’re facing sexual offences, domestic assault, violent crimes, homicide, drug charges, impaired driving, fraud and theft, firearms, bail, youth matters or an appeal, we will help you fight the charge. And if your case can be resolved or withdrawn without ever going to trial, that's what we'll go after first. If it can't, you'll be ready. So will we.
You'll never get an hourly bill. One flat fee for your matter. Call us with a question and it costs you nothing — we'd rather you asked than sat on it.
You can pay as you go. An initial payment, then monthly instalments. Everything you pay counts toward your fee. We accept legal aid certificates on a limited basis.
You can check our work. Withdrawn. Stayed. Acquitted. We publish the charge, the section, the court and the outcome. See our recent results.
Your first hour with us is free. A real hour, not a screening call. You'll leave knowing what you're facing, what happens next, and roughly what it will cost. And if the police have contacted you but you haven't been charged yet, call us before you call them back.
Legal Issues - What to do
“I was so scared, and I was always thinking I have this case against me and how I am going to win this case, how am I going to survive… Whenever I asked questions or whenever I worried … I talked to her she was always there to help me….. She won the case because she is that good, I was in tears I couldn’t say a single word to her, but I said you saved my life” Former Client, Calgary, Alberta

How We Can Help You Beat a Criminal Charge
When you’re in the process of being investigated and charged or looking for someone to represent your loved one, it’s essential to find an experienced criminal defence lawyer who’s ready to protect your rights. Our team has years of legal experience defending clients in criminal court.
Step 1 — We start before your first court date
The first thing we do is tell you what not to do: what not to say to police, what not to post, who not to contact. Then we get the Crown's disclosure and read all of it: officer notes, statements, video, timestamps.
Step 2 — We find the weakness and take it to the Crown
Most cases are not won at trial. They are won when we show the prosecutor a problem in their file - an unlawful search, an unreliable witness, a gap in the evidence — and the charge gets reduced or withdrawn entirely.
Step 3 — If it has to be tried, we try it
Some cases have to be fought. We build every file from day one as though it will be, with Charter applications, experts and cross-examination. The Crown knows we'll take it to trial. That changes what they offer you.

Leanne Scholtens
I dont have much experience with Lawyers, but Jillian is great. It was is a very stressful time and she walked us through everything, step by step. She did everything she needed to do to ensure that we were making the right decisions regarding our situation. Jillian was kind and was always available to answer any questions we had. I would recommend her to anyone, especially with matters involving youth.

Rex Casey
illian Williamson of Wyman & Williamson, provided exceptional legal representation during a very stressful time. She took the time to explain the process, answered all my questions, and fought hard for the best possible result. I could not have asked for a better lawyer.
Nien Nguyen
We need more people like Jillian in this world. She took on our case when others made it difficult. She set expectations early on and worked with us throughout the legal process. We have never had any dealings with the law before this. She gave us hope and really worked hard to get us a positive outcome. I can not say enough good things about her. She even gave us some life advice outside of the legal matters. She is worth every penny she charges. My wife and I are so immensely grateful for Jillian and her team. I highly recommend Jillian for any legal matters.
Rene Rivard
I encountered a OHS regulatory legal issue where my company needed legal representation. I found James and Jillian after having an unfortunate experience with a different lawyer. They were clear and transparent with me and fought hard to get to the best result. Jillian and James are a great team and were effective in the resources and skill each possess. They helped us make an unfortunate situation much more baseball. Highly recommend this team. -RR
Criminal Defence Representation From Investigation to Court
Qualified Lawyers Providing Legal Help in Calgary
A criminal charge doesn't start at the courthouse. It starts with a phone call from police, a search warrant, or a knock at the door, and what you do in those first days often shapes everything that follows. We act for you from that moment through to trial.
We appear in courthouses across Alberta, including Calgary, Airdrie, Canmore, Drumheller, Red Deer, Lethbridge and Edmonton, in Saskatchewan, including Saskatoon and in British Columbia.
In our experience, we have learned how each of these courts actually runs: the Crown offices that prosecute there, how they approach resolution, and what the judges expect from counsel who appear in front of them. Knowing the law is the starting point. Knowing the courtroom is what changes outcomes.
When you choose Wyman & Williamson, we will fight to the ends of the earth for you.
