David Chow, a Calgary criminal lawyer and roadside sanctions lawyer (IRS).

"Don't blindly trust a website or an advertisement (including this one). Any lawyer can sell you online, not every lawyer can properly defend a case". 

I am a criminal defence lawyer and roadside sanctions lawyer. This means that I defend people who are accused off committing offences contrary to the Criminal Code of Canada. I also defend people sanctioned under the Provincial Administrative Penalties Act (roadside sanctions).  Please understand, I am not a divorce lawyer, corporate counsel or a civil litigator (a lawyer who sues). I am only a criminal defence lawyer and roadside sanctions lawyer.

Hiring the right criminal defence lawyer might be the most important decision you ever make. Do not make your decision hastily or without reasonably considering your choice of counsel. The role of defence counsel is multifaceted. A good defence lawyer is not only educated in law and process, he or she must also be an experienced legal strategist who respects the presumption of innocence, Charter rights, the accused's personal and legal jeopardy and the client's financial situation. Even competitively priced legal representation can be expensive. It does not need to be unnecessarily so. Many cases can be resolved without a criminal record in a manner that mitigates the impact on client finances.

Alberta Immediate Roadside Sanctions Lawyer

"In December 2020 the Alberta Government introduced new Provincial impaired driving legislation that in the view of this Alberta criminal lawyer, seriously erodes due process".

His passion for his job is outstanding. He has absolutely incredible attention to detail. He was able to get the trial acquitted without me even having to take the stand. His prep sessions the week before court were very thorough and made us feel at ease because we were prepared for anything. From the very beginning he had a very confident approach to the case. David is extremely knowledgeable, hard working, detailed and an over-all great person. If your looking for a lawyer, your search should end here. We looked into a lot of lawyers and are so happy with our choice. We are forever grateful for his experience and hard work. Thanks so much David.

He got me a very favorable outcome in my case, and was very quick to communicate with me right after he had spoken to crown, and got me a wonderful resolution for my case, which could have gone so much worse. Also he was understanding and kind to me regarding my situation, and made a much more favorable solution to my issues which literally saved me. I'm so thankful for David and his expertise, kindness, and reliability. If myself or anyone I know ever ends up in a situation where legal representation is needed, I will go with and recommend David in half a heartbeat. Thank you so so much, David, from the bottom of mine & my family's hearts. You've done amazing to help me stay on the right path and I'm beyond grateful for you and everything that you've done for me over the last year or so. I can say with 100% certainty that David has saved me from a huge backward slide into a life I've fought so hard to get out of. I can't even express my gratitude to you !

David has been working on my DUI case for the last year and has been extremely helpful and dedicated throughout the entire process. He was very straightforward about his thoughts about why I should fight the charges and broke them all down before I even decided to hire him, allowing me to make my own decision to pursue it or not. David was able to identify key areas of my case and present them to the court which eventually lead to my case being withdrawn and not going to trial. He was always available and constantly kept me updated on how the case was progressing.
