Principes généraux

Voir également: Reasonable and Probable Grounds, Investigative Detention, et Plain View Search and Seizure#Sniffer Dogs

A "suspicion" refers to an expectation that a person is "possibly engaged in some criminal activity."[1]

A suspicion must be reasonable to be lawful, which requires "more than a mere suspicion and something less than a belief based upon reasonable and probable grounds". It must be supported by factual elements that can be independently assessed.[2]

Lower Than "Probable"

Reasonable suspicion is a standard lower than "reasonable and probable grounds."[3] The main distinction is "merely the degree of probability demonstrating that a person is involved in criminal activity, not the existence of objectively ascertainable facts."[4] It refers to the "possibility of uncovering criminality, not the probability of doing so."[5]

It follows that the "degree of reliability and the amount of information to establish that lower threshold is lower" than RPG.[6]

"Reasonable"

The presumption of reasonable suspicion should "not be disturbed unless it is unreasonable or not rationally capable of supporting an inference of suspicion." [7]

Taking Account of Realities of Policing

In evaluating police decision-making, the reviewing judge must "take into account that the police at the scene are often required to make quick decisions based on available information, some of which may not be complete or exact, in situations that are rapidly changing and potentially volatile."[8]

The judge should also account for an officer's experience in the particular type of investigation. The officer's experience may allow him to draw inferences and deductions that regular people would fail to make.[9] However, the court must look "carefully" at what is being claimed as "experience" and "training" to ensure that the integrity of the standard is maintained.[10]

An officer's "educated guess" cannot "supplant" the scrutiny required for reasonable suspicion standard.[11]

Level of Scrutiny

Because it may permit intrusions on zones of privacy, the grounds must be subject to a "rigorous", "independent" and "exacting" level of scrutiny.[12]

Reasonable Suspicion Test

A reasonable suspicion lies between a mere suspicion and reasonable and probable grounds. [1]

Multitude of Conclusions Possible

Reasonable suspicion does not require that it be the only possibility, but merely one possible conclusion based on supported facts.[2] It also means that reasonable suspicion does not need to be the only inference from a particular constellation of factors.[3]

Where suspicion deals with possibilities rather than probabilities it necessarily means that it is possible to reasonably suspect that innocent people are involved in crime.[4]

Reliability and Specificity of Evidence

Reasonable suspicion can rely on information that is less reliable than for establishing "reasonable and probable grounds."[5]

The evidence forming reasonable suspicion need to indicate the "possibility of criminal behavour". The evidence itself need not include unlawful behaviour or evidence of a specific criminal act.[6]

Assessed on Totality of Evidence

The assessment is based on the totality of the evidence-all surrounding circumstances-rather than piece by piece consideration of whether the evidence is consistent with the factors. [7] The inquiry must consider "the constellation of objectively discernible facts said to give the investigating officer reasonable cause to suspect that the individual is involved in criminal activity."[8]

No Obligation to Make Inquiry

The obligation of police to consider all factors does not require them to make inquiry into exculpatory factors or rule out innocent explanations.[9]

Relevant Factors

The suspicion must be "sufficiently particularized" as an overly "generalized suspicion" would capture too many innocent persons.[10] Accordingly, factors that may "go both ways" are not sufficient on their own to support reasonable suspicion.[11] Such factors do not preclude reasonable suspicion arising when they are part of the constellation of factors.[12]

Any factors that are favourable or unfavourable (including "exculpatory, neutral or equivocal") must still be considered as part of the totality of circumstances.[13]

Standard of Review

Determination of whether factors amount to a reasonable suspicion is question of law reviewable on a standard of correctness.[14]

Objective Component

Reasonable suspicion must include objective reasonableness.[1]

The judge is permitted to consider the police officer's training and personal experience in determining objective reasonableness.[2]However, the evidence of a police officer is no less worthy of scrutiny.

The officer himself cannot dictate what is reasonable and what is not. [3]

Observations of a suspect running away from police, on its own, is not enough to allow for police to detain or search.[4]

Compared to Reasonable Grounds

Reasonable suspicion "involves possibilities, not probabilities."[1] Courts must be careful not to conflate the two standards.[2]

Impaired Driving

Voir également: Screening Device

A police officer may demand that a person who is found in care and control or in operation of a vehicle undergo a roadside screening test for alcohol. The officer must have "reasonable grounds" to suspect (or "reasonable suspicion") that alcohol is in their body to make a roadside test demand.[1] The quantity of alcohol and the level of impairment is irrelevant.

Burden of Proof

The burden is on the Crown to prove that there were grounds to administer the test on a balance of probabilities.

Failure to For Grounds

Where an officer administers an ASD without reasonable suspicion, a Charter violation under s. 8 and 9 result. [2]

Sufficiency of Grounds

The standard required for the ASD test under 254(3)(a)(i) is not a “standard of proof” as understood in judicial proceedings.[3]

An admission of having consumed alcohol without mention of when and how much can be considered sufficient to form a reasonable suspicion.[4]

Compelled Statements or Participation

Evidence that was obtained from the accused through his compelled participation can only be used to establish grounds of suspicion and cannot be used to incriminate the accused.[5]

Reasonable Suspicion Test

The standard only requires a belief on the presence of alcohol and not the amount consumed, the effects or degree of impairment.[1]

The suspicion is of the "consumption alone and not its amount or behavioural consequences."[2]

Multiple Officers Involved

The officer who makes the demand does not need to be the officer who had initial contact with the accused.[3] However, the officer making the demand must be the one who formed a reasonable suspicion that the accused has alcohol in his system.[4] This basis can be based on information received from another officer.

Totality

The requirement of considering the totality of circumstances requires considering not only evidence suggestive of alcohol in the body but also evidence suggesting otherwise as well as the absence of evidence.

The objectively verifiable evidence should not be dissected and individually tested.[5]

Source of Alcohol

An officer should be able to describe the origin of the alcoholic smell, by indicating whether other people were in the car, or otherwise suggesting where the source of the odor could be from.[6]

It is not necessary that the crown eliminate all other possible sources of the odor of alcohol to form reasonable suspicion.[7]

Requirements for Reasonable Suspicion

For the peace officer to form reasonable suspicion, the officer must:[8]

  • subjectively and honestly suspect the driver who had alcohol in his body; and,
  • The subject of suspicion must be based on "objectively verifiable circumstances"

Reviewing the grounds requires the application of the Mackenzie test: "what a reasonable person, standing in the shoes of the investigating police officer and aware of all the objectively verifiable evidence, reasonably suspect the driver had alcohol in his or her body?"[9]

Subjective Component

There should not simply be signs of consumption of alcohol, but also signs of impaired driving skills. Once both are established, the analysis must consider the degree of each and the totality of the circumstances. [1]

Impairment to driving skills requires that on an objective basis there is impairment “such as coordination, comprehension and a poor (but not simply illegal) driving pattern.” If any one of these is found as well as evidence of alcohol consumption, then there is an objective basis to conclude the driver’s ability to drive is impaired by alcohol.[2]

Alternate explanations or imprecise descriptions do little to reduce the value of the observations. This is because the observations to not need to meet a formal burden of proof. Also, most any signs can be explained by something other than alcohol.[3]

An admission of "two drinks", without any indication of the time of these drinks, was enough to support a reasonable suspicion.[4]

An admission of “two drinks” is not relevant to establishing impairment. It is only where there is an admission of many drinks, that the inference of impairment can be made.[5]

Evidence of an amount of consumption can also be enough to create a reasonable suspicion.[6]

Grounds should include more than simply an admission of the accused that they had drank alcohol within the past three hours. [7]

Objective Component

The grounds need not be proven a on balance of probabilities.[1]

To be reasonable it does not need to be the only conclusion derived from the circumstances. The court considers whether a reasonable person in the circumstances would have a suspicion that the person was impaired by alcohol.

The smell of alcohol on the breath of the driver, by itself, is sufficient to support the suspicion that the driver was operating the vehicle while impaired.[2] Or the suspicion that there was alcohol in their body.[3]

However, the smell of acohol in the vehicle does satisfy the objective grounds to use the screening device.[4]

It is not necessary to consider the timing at which the suspected alcoholic beverage was consumed.[5]

The lack of evidence of consumption can weigh against the formation of a reasonable suspicion.[6]

An officer need not spell out his subjective suspicion that there is alcohol in the accused’ body using the words of s. 254(2). The court may infer the suspicion based on all of the evidence.[7]

It is generally considered that the “point in time” for the issue of reasonable grounds is at the time of the arrest. Certain cases have concerned the moment being at the time at the time of the demand.[8]

If the accused had drank alcohol within 15 minutes of the first test may render the ASD test unreliable. The mere possibility of consuming alcohol within 15 minutes does not affect the reliability of the ASD.[9] The main issue is whether there was any evidence which may have caused the officer to investigate when the accused had his last drink. If "credible evidence" exists the officer should delay test for 15 minutes to ensure reliability.[10]

Sniffer Dogs

Voir également: Plain View Search and Seizure

"Sniffer dog" searches, most typically seen at border-crossings including airports, can be permitted on the standard of reasonable suspicion.[1]

For a sniffer dog search to be valid, the court must ask itself:[2]

  1. did the officer subjectively believe that there were reasonable grounds to suspect that the accused was in possession of the drugs?
  2. were there sufficient grounds to reasonably suspect the accused was in possession of drugs?

Reasonable suspicion in this circumstances requires an "expectation" that the accused is "possibly engaged in some criminal activity. As well, the suspicion must be supported by facts that can be subject to review."

As part of the determination of reasonable suspicion it includes the presence of a "masking agent" such as perfumes, colognes or other odour producing products. [3]

Drug Trafficking

Observation of someone stopping at a suspected drug house, by itself, is not sufficient to form a reasonable suspicion authorizing detention.[1] However, where the status of the house as a drug house is well-founded, a reasonable suspicion standard is sufficient.[2] Indeed, with the right circumstances, there may even be sufficient grounds to arrest.[3]

A observed hand-to-hand exchange in isolation can only amount to a suspicion and nothing more as it may equally be an innocent exchange of small objects.[4]
