Kitchener, Ont.The Intoxilyzer 9000 is, in Ontario's impaired-driving enforcement apparatus, the instrument of record. It is the machine that produces the number. The number, on a charge of impaired operation with a blood alcohol concentration over eighty milligrams per one hundred millilitres of blood, is the charge. Without the number, there is no over-eighty charge. The legislative provision, section 320.14(1)(b) of the Criminal Code, says "blood alcohol concentration is equal to or exceeds 80 mg of alcohol in 100 mL of blood." The provision requires a measurement. The measurement, in the standard enforcement sequence, is produced by the Intoxilyzer. The machine provides the Crown its case.

The machine, on the afternoon of March 15, 2026, at a police station in this city, was calibrated and operated by a certified breath technician, Surjee #1752, who signed the printout at 15:41. The calibration check produced 099 milligrams, one off target, within the acceptable range. The technician ran a Subject Test on the accused at 15:44. The Subject Test is the test that matters. The Subject Test is the one that measures the accused's own breath and produces the number that becomes the Crown's evidence. The Subject Test, on Intoxilyzer 9000, serial number 90-004868, on March 15, 2026, at 15:44, produced exactly one number. The number was zero. Zero milligrams of alcohol per one hundred millilitres of blood. The machine read zero.

This is the only breath test result on the file. There is no second test. There is no blood sample. There is no toxicology. There is no ASD result. The administrative licence suspension that was issued on the day of the arrest was issued for the ground of refusal, not for a reading at or above eighty milligrams, because there is no such reading. The suspension document, in its own language, confirms that the basis is refusal. The absence of a blood alcohol reading is confirmed by both the Intoxilyzer printout in Crown disclosure and by the Ministry of Transportation administrative notice, which are independently consistent: no BAC, because the test returned zero.

What the charge requires

Section 320.14(1)(b) of the Criminal Code is colloquially described as "over eighty." The full text of the provision makes clear that it requires a concentration, a specific, measured amount of alcohol per unit of blood. The provision does not charge a person with having been in a car while something might have happened. It charges a person with having had a blood alcohol concentration at or above a specific threshold at the time of operating or having care and control of a motor vehicle. The charge is defined by its measurement. The measurement is the evidence. Without the measurement, the provision has nothing to attach to.

The Intoxilyzer 9000 is a certified instrument whose results, under section 320.31 of the Criminal Code and its predecessor provisions, are admissible in evidence under a certificate of analysis when the instrument was properly operated and maintained. The certificate of analyst on this file certifies the alcohol standard solution used with the Intoxilyzer 9000 as of July 15, 2025. The certificate is formally adequate. The instrument was certified and maintained. The breath technician is certified. The process was followed. The process produced a result. The result was zero. There is nothing for the certificate of analyst to support, because the Subject Test produced no reading that could be above eighty milligrams, because the Subject Test produced zero milligrams.

The machine read zero. There is a zero on the file. There is an over-eighty charge on the same file. The country allows these two things to coexist.

What the country does with a charge that has no evidence

The Crown's discretion to proceed with or withdraw a charge is governed by the standard that, in the terminology of the federal public-prosecution service and its provincial counterparts, has been expressed as whether there is a reasonable prospect of conviction. The test is prospective: not whether the Crown has already proven the case, but whether, on the evidence available, a trier of fact could reasonably return a conviction. The test is applied at the charge-screening stage by the Crown attorney who reviews the police file and decides whether to proceed. The test is supposed to be applied honestly and continuously throughout the proceeding, including at the point when new evidence, or the absence of evidence, becomes apparent.

A charge of impaired operation over eighty milligrams, on a file where the Intoxilyzer Subject Test returned zero milligrams, does not, on any honest application of the reasonable-prospect-of-conviction standard, have a reasonable prospect of conviction on the over-eighty count. The Crown cannot prove a blood alcohol concentration at or above eighty milligrams when the only blood alcohol measurement on file is zero. This is not a difficult analysis. This is arithmetic applied to an evidentiary standard. The charge should not have passed charge screening. The charge is on the information. The matter is before the court. The accused has an appearance scheduled for June 23, 2026.

The refusal charge and the zero

The matter includes a separate refusal count under section 320.15(1) of the Criminal Code. The refusal count and the over-eighty count are, in this file, not the same charge. The refusal count alleges that the accused failed or refused to comply with a breath demand. The over-eighty count alleges a blood alcohol concentration at a specific level. These are independent allegations. The existence of a refusal count does not rehabilitate the over-eighty count. If anything, the presence of a refusal count in the same information as an over-eighty count, on a file where the Intoxilyzer returned zero, creates an evidentiary record that is self-contradictory on its face: the charge sheet asserts that the accused both had a blood alcohol concentration over eighty milligrams and refused to provide a breath sample. The machine that the accused provided a sample to returned zero. The certificate of analyst that the Crown relied on covers the instrument that produced zero. The information asks the court to consider all of this at the same time, without apparent tension.

What should happen and what has happened

What should have happened is that the charge screening Crown who reviewed this file, upon encountering a Intoxilyzer Subject Test result of zero milligrams, withdrew the section 320.14(1)(b) count. What has happened is that the section 320.14(1)(b) count remains on the information. The accused has been attending court on this information, under the terms of a release order that restricts his movements and his use of any motor vehicle, since March 15, 2026. The accused has had a Crown pre-trial, an appearance on May 19, a follow-up on May 22, and has a next appearance on June 23. At no appearance has the section 320.14(1)(b) count been withdrawn on the basis that it has no evidentiary foundation. At no appearance has the Crown produced a blood alcohol reading to support the count. The count is on the information. The machine read zero. These two things have coexisted in the Kitchener courthouse for ninety days.

The verdict

The machine read zero. The charge says over eighty. The country's criminal law requires the Crown to have a reasonable prospect of proving the charge to proceed with it. The country's criminal courts have, for three months on this file, not been told by the Crown that the over-eighty count has no evidentiary foundation, and withdrawn it. The accused has driven no vehicle since his release order was signed. The accused has reported to bail supervision. The accused has attended every appearance. The machine, in the meantime, says zero. It has said zero since 15:44 on March 15, 2026. It will continue to say zero, because zero is what it measured, and there is no other measurement on the file.

Withdraw the count. The machine said zero. That is the case.
