Why community cooperation matters after serious crashes
Every serious collision in this region represents a chain of human stories — families disrupted, first responders tested, and investigators working to reconstruct moments that changed lives. While officers rely on scene evidence and technical reconstruction, community cooperation often provides the missing context. A single dash-camera clip or memory of what happened just before impact can reveal crucial timing, clarify responsibility, or even exonerate a driver wrongly accused.
Across Hamilton, London, Windsor, and the communities in between, Ontario police services have repeatedly emphasized how much they depend on members of the public to share what they know. Your insight — no matter how small — may help another family find closure or allow justice to be done.
