The defendant was charged with operating a motor vehicle with a blood alcohol level exceeding 80 milligrams of alcohol in 100 millilitres of blood on January 30, 2018.
A York Regional Police officer observed the defendant entering an intersection as the light turned red, conducted a traffic stop, and detected the smell of alcohol on her breath.
The defendant provided a failed Approved Screening Device (ASD) test and was arrested.
Two breath samples at the station showed readings of 110 milligrams.
The defendant challenged the lawfulness of the stop and the admissibility of the breath test results under the Charter.
The court found the officer credible, accepted that there was a valid reason for the traffic stop and reasonable suspicion of impairment, and admitted the breath test evidence.
The defendant was found guilty.
