Students, faculty, and staff at the University of Victoria are mourning the loss of two students killed in a bus crash on Vancouver Island.

They were on their way to the Bamfield Marine Science Centre when the vehicle rolled over last night.

"Our heartfelt thoughts go out to the students’ families and loved ones, to whom we offer our sincerest condolences," UVic president Jamie Cassels said in a statement. "We also grieve with those closest to these members of our campus community, including roommates, friends, classmates and professors who were in contact with them during their time on campus."

The university is not disclosing any personal information about the deceased students.

The Joint Rescue Co-Ordination Centre has stated that there were about 40 adults on the bus. (Later in the day, it was reported that there were 48 people on the bus.)

Three have been airlifted to hospital with serious or critical injuries.

"Cormorant SAR helicopters were unable to land at accident site and were repositioned to Port Alberni Airport," the JRCC stated on Facebook. "B.C. Ambulance Service transported injured from the crash site to the airport where they were airlifted to hospital."

Bamfield is on the western point of Vancouver Island on a twisty and, depending on the weather conditions, treacherous road.
