Three other men were also killed.
Dr. Ken Gellatly, an optometrist in Calgary, has died in a plane crash.
Three other people also died in the crash Thursday evening near Kelowna, British Columbia, CBC News reports. They were Jim Prentice, former premier of Alberta; Jim Kruk, a retired officer of the Royal Canadian Mounted Police; and Sheldon Reid, a retired Calgary businessman.
The men were traveling in a 1974 Cessna Citation jet that crashed eight minutes after takeoff, Canadian authorities said.
Kruk was the pilot of the plane headed from Kelowna to Springbank airport, not far from Calgary. There were no survivors.
In addition to his role as an optometrist, Gellatly served part-time on the faculty of the Vision Care Institute, according to CBC.
Authorities are investigating the cause of the crash.
