Driver accused of deliberately striking pedestrian on Nonquon Road
Durham Regional Police say a 36-year-old man remains in critical, life-threatening condition after he was struck by a vehicle that allegedly crossed into oncoming traffic in Oshawa on Thursday, Aug. 6.
The collision occurred at about 10:30 a.m. in the area of Nonquon Road and Mary Street North, according to investigators. Police say a black Volkswagen sedan travelling northbound left its lane and accelerated into the oncoming lane, where it struck the pedestrian.
Emergency crews discovered the injured man at the scene and he was airlifted to a Toronto-area trauma centre. Durham police described his injuries as critical and life-threatening.
Suspect located after vehicle found nearby
Investigators from the Durham Police Collision Investigation Unit later located the suspect vehicle parked and unoccupied in the vicinity. Police executed a search warrant at a residence overnight and arrested the suspect at about 12:40 a.m. on Friday, Aug. 7, without incident.
The accused has been identified in court documents as Carter William Boyce, 28, of Oshawa. He faces three charges:
- Dangerous operation — cause bodily harm
- Aggravated assault
- Fail to remain at accident — cause bodily harm
Next steps: court and witness appeals
Boyce was held for a bail hearing, police said. The investigation remains active and officers are asking anyone with relevant footage or information to come forward.

Police investigators have asked anyone who may have captured the incident on a cell phone, dash camera, or security camera to contact Det. Chambers of the Central East Division Criminal Investigations Branch at 1-888-579-1520, ext. 1705. Anonymous tips can be submitted to Durham Regional Crime Stoppers at 1-800-222-8477 (TIPS).
The collision and arrest raise immediate public-safety and community concerns in Oshawa, where residents and commuters rely on a patchwork of arterial and local streets connecting suburban neighbourhoods and employment areas. The stretch of Nonquon Road north of the 401 serves both local traffic and industrial access, and a serious incident there can quickly affect traffic flow and community confidence.
As investigators piece together the sequence of events, questions remain about motive, the relationship between the suspect and victim, and whether impairment or other factors played a role. Durham police have confirmed the two individuals are known to each other, but have not released further details while the probe continues.
For residents, the case underscores the value of community vigilance. Dash cams and home surveillance increasingly play a central role in collision reconstruction and in bringing clarity to hit-and-run cases. Police ask that anyone with footage preserve it and report it promptly.
This is an active criminal investigation. WE NEWS will follow court proceedings and any updates from Durham Regional Police as they become available.
