Fatal Multi-Vehicle Crash at March Road and Diamondview Road

Tragic motor vehicle accidents on rural and suburban roadways can completely upend families in a matter of seconds. On the evening of August 21, 2026, at approximately 5:42 p.m., a severe multi-vehicle collision occurred at the busy intersection of March Road and Diamondview Road, south of Carp in Ottawa’s west end. The devastating three-vehicle crash prompted a massive response from emergency services, closing the intersection for several hours. Tragically, a 31-year-old woman was pronounced dead at the scene, while another 37-year-old woman sustained serious injuries and was airlifted to the hospital.

The Ottawa Police Service Fatal Collision Investigation Unit launched an extensive investigation into the factors leading up to the crash. Investigators have actively sought witnesses and dashcam footage from anyone who travelled through the March Road and Diamondview Road corridor. Navigating the aftermath of a catastrophic multi-vehicle accident involving severe injuries or fatalities is an overwhelming ordeal. Families are immediately forced to cope with unimaginable grief, sudden medical emergencies, lost income, and intense stress while dealing with insurance companies and complex legal hurdles.

Injured survivors and grieving families navigating these complex circumstances do not have to handle the burden alone. Securing knowledgeable legal guidance early ensures that critical evidence is preserved, rights are fully protected, and victims or their dependents receive the comprehensive support and compensation necessary for recovery and long-term financial security.
