The defendant was charged with impaired operation and refusing to provide a breath sample following a traffic stop on September 2, 2012.
A police officer observed the defendant's vehicle exhibiting poor driving behavior on the Queen Elizabeth Way and conducted a traffic stop.
The officer observed various indicators including glassy eyes, an odour of alcohol on the defendant's breath, unsteadiness on her feet, and difficulty putting on high-heeled shoes.
The defendant admitted to consuming one glass of wine approximately two hours earlier.
The officer arrested the defendant for impaired operation without administering an approved screening device.
The defendant challenged the arrest on Charter grounds, alleging the officer lacked reasonable and probable grounds and that her detention was arbitrary.
The court found, by the barest of margins, that the officer did not have objectively tenable grounds to make the breath demand and dismissed both charges.
