Successfully defending an impaired driving charge at trial requires sharp attention to police procedure, timing, and the technical limits of evidence. These cases often rest on breathalyzer results, roadside screenings, officer observations, and timelines that must align with strict legal standards. We examine the arrest from the moment of vehicle stop through detention and demand, looking for breaches of your Charter rights or weaknesses in the Crown’s case. No two impaired trials are the same, and our courtroom strategy adapts accordingly—targeting the details that create doubt and pursuing exclusion of evidence where possible.
