The appellant appealed a conviction for driving with a blood alcohol concentration exceeding 80 mg.
The trial judge had found that the police failed to make the formal breath demand as soon as practicable under the Criminal Code, constituting a s. 8 Charter breach, but admitted the certificate of analysis under s. 24(2).
On appeal, the appellant argued that the failure to make the demand promptly should disentitle the Crown from relying on the presumption of identity and that the certificate should have been excluded.
The court held that the presumption of identity under s. 258(1)(c) remains available even if the demand was not made as soon as practicable, and that the proper remedy for any breach lies under the Charter exclusion analysis.
Applying the Grant framework, the trial judge’s decision to admit the evidence was entitled to deference and disclosed no error.
