The Halton Regional Police Service Collision Reconstruction Unit (CRU), a branch of Forensic Identification Services, is responsible for the investigation and reconstruction of all motor vehicle collisions that result in life-threatening/life-altering injuries or death. There are seven members - one Sergeant and six Detective Constables - in the CRU.

Each Detective Constable assigned to the CRU has received specialized training over a number of years. This expertise enables them to determine causes, calculate speeds and reconstruct motor vehicle collisions.

CRU members also provide expert testimony in criminal and civil courts of law, allowing judges, juries and the families of victims to better understand what occurred at the scene of a collision. These in-depth investigations conducted by members of the CRU provide explanations as to how and why collisions occurred and who is responsible.
