Criminal law 2016 ONCA 828

R. v. Puvtoski

The Court dismissed the leave application because the officer's observation of odour alone provided reasonable grounds for an ASD demand and the identity of the driver was established without reliance on the appellant's statements; therefore no significant legal error under s.7 arose and the appeal lacked significance beyond the case.

  • Self-incrimination
  • Compelled statements
  • Approved screening device (asd) demand
  • Breathalyzer
  • Odour evidence
  • Leave to appeal test

Criminal law 2016 BCSC 1336

R. v. Turko

Appeal from a summary conviction for over‑80 driving was allowed because the trial judge failed to consider all evidence before the breath demand.

  • Impaired driving
  • Breathalyzer/asd screening device
  • Reasonable and probable grounds
  • Section 254(3) demand
  • Section 8 charter (search and seizure)
  • Section 24(2) exclusionary rule

Criminal law 2010 ONCA 442

R. v. Chow

Because the Crown called viva voce testimony of the Intoxilyzer technician and filed the certificate, the trial judge was entitled to consider the test results and surrounding circumstances in assessing the credibility of the defence; the presumption of accuracy need not have been relied upon and there was no legal error. The appeal is dismissed.

  • Breathalyzer
  • Presumption of accuracy
  • Carter defence (evidence to the contrary)
  • Bill c-2 retrospective application
  • Judicial notice

Criminal law 2009 ONCA 766

R. v. Mulroney

Where no approved container has been designated, s.258(1)(c)(iii) must be read to require that breath samples be received directly from the accused into an approved instrument; because the statutory proof is conclusive, the provision must be strictly construed, and uncontradicted circumstantial evidence from a qualified technician that the accused blew into the instrument mouthpiece and the instrument was working properly is sufficient to allow a trier of fact to infer direct receipt and sustain a conviction.

  • Breathalyzer
  • Conclusive proof
  • S.258(1)(c)(iii)
  • Directly into approved instrument

Criminal law 2008 SCC 16

R. v. Gibson

The Court considered whether “straddle evidence” and post-offence elimination tests could rebut the Criminal Code presumption for driving over 80 mg BAC.

  • Breathalyzer
  • Statutory presumption
  • Expert evidence
  • Blood alcohol concentration
  • Post‑offence testing
  • Section 258(1)(d.1)

Criminal law 2007 BCSC 1873

R. v. Milos

The court dismissed an impaired-driving appeal, holding the ASD demand was valid despite the crash rendering the car inoperable and the breath samples were taken as soon as practicable.

  • Care or control
  • Approved screening device
  • Section 254(2) criminal code
  • Section 254(3) criminal code
  • As soon as practicable
  • Delay in testing

Criminal law 2007 BCSC 839

R. v. Lock

Appeal from summary conviction in a drinking-and-driving case. The court held the trial judge misapprehended expert evidence on Count 2 and ordered a new trial.

  • Impaired driving
  • Over .08 offence
  • Misapprehension of evidence
  • Reasonable doubt
  • Expert opinion on alcohol absorption
  • Admissibility and weight of accused's out-of-court statements

Criminal law 2007 ONCA 199

R. v. Keval

The appeal is dismissed because, aside from one tenuous reason identified by the summary conviction appeal court, the trial judge's credibility findings were supported by the record and were not so tenuous or misinterpreted as to amount to reversible error; the ineffective assistance claim was unsupported by evidence and proposed measures would not have assisted the defence.

  • Credibility findings
  • Ineffective assistance of counsel
  • Intoxication
  • Breathalyzer
  • Summary conviction appeal

Criminal law C43848

R. v. Vanderbruggen

The Crown adduced sufficient evidence that the delay was reasonable in all the circumstances (arrest, transport, waiting for technician, search, informing and machine preparation), so the breath samples were taken 'as soon as practicable' under s.258(1)(c)(ii); the trial judge's factual finding stands and the appeal is dismissed.

  • Breathalyzer
  • Presumption of identity
  • Section 258(1)(c)(ii)
  • As soon as practicable

Criminal law 2005 NSPC 67

R. v. Gray

The approved screening device result and subsequent breathalyzer evidence were obtained outside the scope of s.254(2) because the breath sample was not provided 'forthwith' (delay ~59 minutes from initial detention); the detention and seizure thus breached ss.8 and 9 and the s.10(b) rights were not fully observed; under s.24(2) the evidence is excluded and the accused is acquitted of s.253(a) and s.253(b) offences.

  • Impaired driving
  • Approved screening device (asd)
  • Breathalyzer
  • Detention and investigative detention
  • Right to counsel (s.10(b))
  • Search and seizure (s.8)
