The accused was charged with impaired operation and "over 80" operation of a motor vehicle following a traffic stop on Highway 404.
The Crown relied on breath test results showing blood alcohol concentrations of 150 mg/100ml and 140 mg/100ml.
The defence challenged the lawfulness of the arrest and breath demand under sections 8 and 9 of the Charter, alleging the arresting officer lacked reasonable grounds.
The defence also alleged a breach of section 10(b) rights regarding privacy during consultation with duty counsel.
The trial judge found the officer's testimony regarding grounds for arrest was riddled with anomalies, implausibilities, and internal inconsistencies, and rejected most of the officer's evidence concerning indicia of impairment.
The court found the officer lacked reasonable grounds for the arrest and breath demand, constituting a Charter breach.
The court excluded the breath test results under section 24(2) of the Charter, finding the breach was serious and compounded by misleading testimony.
Without the breath evidence, the Crown could not prove impaired operation beyond a reasonable doubt.
Both charges were dismissed.
