About XPolice Hamilton
XPolice Hamilton – Over 20 Years of Dedicated Traffic Defence
Our Hamilton office has been helping drivers fight traffic tickets and provincial offences since 2003. From the beginning, the mission has been clear: to provide experienced, honest, and strategic defence to everyday people facing driving and regulatory charges.
The legal system was meant to be straightforward for the average person — but it’s not. The process is confusing, the penalties are serious, and even a simple mistake can cost you your licence, your job, or your record. That’s where we come in.
In 2016, the office became locally owned and operated by Steve Petersen, a retired officer with over 30 years of law enforcement experience. He was later joined by Greg Zafirides, also a retired officer with more than 30 years on the force. Together with our team of licensed paralegals, we’ve become one of the most trusted names in traffic ticket defence in Southern Ontario.
Our reputation is known to the courts, to the police, and to the public — and we’re proud to carry that legacy forward.
