Motorcyclist Dies in Collision on Sarnia Road in London

,

A motorcyclist died after a collision with another vehicle at Sarnia Road and Castlegrove Boulevard in northwest London Monday night. All drivers involved remained at the scene.

What Is Known About This Fatal Motorcycle Crash

According to CTV News London and the London Free Press, emergency crews responded to the crash at around 8 p.m. Monday. The motorcyclist was taken to hospital with critical injuries where he later died.

All drivers involved remained at the scene, and police have not said whether any charges are pending. The investigation has been reassigned to the London Police Service’s Road Safety Section and remains ongoing.

Police Ask for Video Footage from a Narrow 35-Minute Window

Investigators are specifically asking anyone who may have been in the area between 7:45 p.m. and 8:20 p.m. Monday and who also witnessed the collision to contact police with any details you may be able to provide. They are also asking bystanders or businesses who may have captured dashcam, residential, or business surveillance footage to come forward.

Why Drivers Staying at the Scene Matters Under Ontario Law

Ontario’s Highway Traffic Act requires every driver involved in a collision to stop and remain at the scene, provide their information, and offer help if anyone is injured. The fact that police specifically noted all drivers stayed is a meaningful detail, since leaving the scene of a serious crash may incur criminal charges under Ontario’s criminal code.

Remaining at the Scene Doesn’t Decide Fault

Staying at the scene satisfies a driver’s legal duty to police, but it says nothing about who was actually responsible for causing the crash. First responders document the scene in a police report, which also supports a case you may later file, but it still does not provide all the evidence you may need.

While remaining at the scene and cooperating with police is appropriate, it does not determine who may be liable for the crash.

Why Police Are Canvassing Such a Specific Timeframe

Police asked specifically for anyone who may have been in the area where the crash occurred between 7:45 p.m. and 8:20 p.m. Monday. That is a 35-minute window that starts well before the crash itself. Asking for footage from before the moment of impact, not just after it, gives more insight into how investigators try to reconstruct the full sequence of events leading up to a collision, and not just the wreckage and debris from the crash scene.

What This Kind of Footage Can Show

Dashcam and surveillance footage showing what happened right before a crash can reveal critical details that aren’t available anywhere else:

Vehicle speed and positioning: Footage from surrounding traffic can show how fast each vehicle was travelling and where they were positioned before the collision.

Traffic signal timing: Video from nearby businesses or homes can confirm whether a light was red, yellow, or green at the relevant moment.

Road and lighting conditions: Footage captures real conditions at the time, rather than conditions reconstructed after the fact.

Why This Evidence Doesn’t Last Forever

Many dashcams and home security systems automatically overwrite older footage within days or weeks. That makes early requests from police, and any request from a family’s own lawyer, more time-sensitive than for other evidence, like medical records.

Frequently Asked Questions After a Traffic Accident

Does it matter that all drivers stayed at the scene instead of fleeing?

It matters for the criminal investigation, since leaving the scene of a serious collision carries its own separate charges. It doesn’t determine who was at fault, which is assessed independently through the evidence gathered.

No charges have been laid yet. Can our family still look into a claim?

Yes, a civil claim doesn’t depend on criminal charges being filed. A lawyer can begin gathering and preserving evidence independently while the police investigation continues.

We think someone may have dashcam footage of the crash. What should we do?

Reach out as soon as possible, since dashcam and surveillance footage is often automatically overwritten within days or weeks. A lawyer can help identify and formally request footage before it’s lost.

Why was this case reassigned to a specialized Road Safety Section?

Serious or fatal collisions are often handled by officers trained specifically in traffic investigation and reconstruction. That level of investigation can produce detailed evidence that also becomes relevant to a civil claim.

How long do we have to look into legal options after a fatal crash in Ontario?

In most cases, Ontario law allows two years from the date of death to file a claim. It’s best to speak with a lawyer as early as possible, so evidence like witness footage isn’t lost.
