The law does not simply require a driver to stop at any location or at the first possible instant regardless of circumstances. Section 320.17 uses the phrase “as soon as is reasonable in the circumstances.” The circumstances surrounding the alleged delay can therefore matter.

A defence review may consider where the vehicle was located, traffic conditions, road design, visibility, weather, the presence of pedestrians, the driver's ability to identify the police vehicle and whether stopping immediately would have created a safety concern.

This does not mean that a driver can disregard a lawful police pursuit whenever stopping feels inconvenient. The question is whether the circumstances provide a legally meaningful explanation for why the vehicle did not stop as soon as was reasonable. The analysis is highly fact-specific.

One issue in some cases is whether the evidence establishes that the accused was being pursued by a peace officer at the relevant time. Police may rely on emergency lights, sirens, vehicle positioning, radio communications, observations and other evidence to establish a pursuit.

The defence can examine what the officer did, what signals were given, how long the pursuit lasted and what the driver could reasonably have perceived. Video footage, dispatch records, dashcam evidence and other objective material may be important when assessing the sequence.

A police officer's conclusion that a pursuit occurred is not necessarily the end of the analysis. The court considers the evidence as a whole.

A flight-from-police allegation can arise alongside other criminal or driving charges. Depending on the circumstances, the prosecution may allege dangerous driving, impaired driving, driving while disqualified, obstruction-related conduct, property offences or other offences.

Each charge has its own legal requirements. An allegation that a driver failed to stop does not automatically establish dangerous driving or impaired driving. The evidence supporting each separate charge should be examined independently.

Where multiple allegations arise from one incident, the defence strategy should consider how the evidence overlaps and whether weaknesses in one part of the prosecution's case affect another allegation.

Some flight-from-police cases involve allegations of high speed, abrupt lane changes, running red lights, driving through intersections or other conduct described as dangerous. These allegations can increase the seriousness of the case.

The defence should examine the driving in context. Traffic, road conditions, visibility, speed, duration of the pursuit and the actual movements of the vehicle can all be relevant. Video and other objective evidence may provide a different picture from a generalized description of the driving.

A collision or near miss does not automatically prove every element of dangerous driving. If dangerous driving is separately charged, the prosecution must prove that offence according to its own legal requirements.

Driver identity can become an issue where police did not immediately stop the vehicle or where the vehicle was shared by multiple people. The prosecution must establish the required elements against the accused person.

Evidence may include direct police observations, video footage, vehicle registration information, witness evidence and statements. Ownership or registration of a vehicle does not necessarily establish who was driving at a particular moment.

If more than one person had access to the vehicle, tell your lawyer about the circumstances. The available evidence should be assessed carefully rather than assuming that the registered owner is automatically responsible for the alleged driving.

Depending on how the investigation unfolded, Charter and procedural issues may also arise. A defence lawyer can review the circumstances of any detention or arrest, statements obtained from the accused, searches or seizures and other investigative steps.

The Canadian Charter of Rights and Freedoms protects important rights during police investigations. Whether a breach occurred depends on the circumstances and applicable legal requirements.

Where a potential Charter breach is identified, the appropriate remedy depends on the nature of the breach and the evidence affected. These issues should be assessed as part of the overall defence strategy.
