Vehicle submersion incidents can happen quickly and often involve a combination of trauma, water exposure, and medical distress. Knowing what to do if a car enters the water and how to respond when someone is unresponsive is critical. In Canada, first aid training emphasizes rapid rescue (if safe), CPR, and immediate emergency response.

Scenario: Vehicle Submersion in the Sumas River, Abbotsford

A tragic incident occurred in Abbotsford, British Columbia, when a vehicle entered the Sumas River near McDonald Park.

Bryan Volden, a 65-year-old man, had just left McDonald Park at the end of No. 3 Road, north of Highway 1, when his 2002 PT Cruiser suddenly veered off the roadway. The vehicle struck wooden posts, traveled across the parking lot, and entered the water, becoming more than halfway submerged.

According to Abbotsford Police Constable Ian MacDonald, it is believed that Volden may have experienced medical distress prior to the crash.

A bystander at the scene acted quickly. A 45-year-old man broke a window of the submerged vehicle and pulled Volden out of the water to safety. Recognizing that he was unresponsive, the bystander immediately began CPR.

Emergency responders soon arrived and took over life-saving efforts. Despite the rapid response and continued care, Volden was later pronounced deceased.

The family later expressed their wish to meet the Good Samaritan who attempted to help. Police have been working to arrange contact. It was also shared that Volden had a history of heart-related health conditions, including prior heart attacks and surgery.

This incident highlights the critical role of bystanders in emergency situations and how quickly events can unfold near water.
