The appellant appealed his conviction for impaired operation of a conveyance and driving with a blood alcohol level over 80 mgs/100 mL.
The Crown conceded a s. 8 Charter breach because the arresting officer did not have an approved screening device (ASD) on scene when making the breath demand, as per R. v. Breault.
The trial judge found consequential s. 9 and 10(b) breaches but declined to exclude the evidence under s. 24(2) of the Charter, citing the officer's good faith error due to a change in law.
On appeal, the court re-evaluated the s. 24(2) Grant analysis, excising the ASD result as required by R. v. Zacharias, which led to findings of unlawful arrest, detention, and breath samples.
Despite these breaches, the court upheld the trial judge's decision not to exclude the evidence, finding that the seriousness of the state conduct and impact on the appellant's rights were outweighed by society's interest in adjudication on the merits, particularly in impaired driving cases.
The appeal was dismissed.
