Emergency crews were called to a BC Ferries terminal in the Gulf Islands early Friday morning after a pickup truck slammed into a railing and plunged into water.

Two people were in the van when it was traveling between births at the Denman Island terminal shortly before 6:45 a.m., authorities said.

The cause of the accident is unclear, but a BC Ferries spokesperson said the vehicle “was not in the loading lanes” before the incident.

“Our crew responded immediately and members were able to throw life preservers into the water and bring both occupants of the vehicle to shore,” Sheila Reynolds told CTV News in a statement.

“Fortunately, none of our staff or crew members were injured in the incident and there was no damage to the vessel or operational ramp.”

British Columbia Emergency Health Services said paramedics were called to the terminal and assessed the two occupants, one of whom was treated at the scene and then transported to hospital.

Operations at the terminal were suspended and sailing times were changed while engineers inspected the dock and a ferry that was docked at the time.

“We appreciate our customers’ patience and understanding as we have taken the necessary steps to ensure a safe environment before resuming service,” Reynolds said. “The ship resumed normal operations, but the route was late.”
