Ottawa-area residents who regularly drive Eastern Ontario's rural highways toward Cornwall are absorbing news of a fatal three-vehicle collision that killed three people Thursday night in South Glengarry Township, southeast of Ottawa.
What happened

Who died

Road closures and investigation
SD&G OPP say the investigation into the cause of the crash is ongoing, and they are asking anyone with information or dashcam footage relevant to the incident to call 1-888-310-1122.
What led here
This is the latest in a string of serious crashes on the rural highways east of Ottawa this year. In August, ottown's earlier report covered the death of a 77-year-old Cornwall man in a motorcycle collision in North Glengarry Township, while a fatal crash in South Stormont in July killed a 16-year-old girl and sent two others to hospital, as detailed in ottown's earlier report.
