An aircraft carrying former Alberta premier Jim Prentice and three other people crashed last night in southern British Columbia killing everyone on board.
Prentice's family confirmed that he was on board the small jet that was en route from Kelowna to the Springbank airport, outside Calgary.
His daughter's father-in-law, Ken Gellatly, was also on the plane.
In a statement, the family says losing two people at once is ``unbelievably painful.''
The 60-year-old Prentice was also a former federal cabinet minister.
Prentice quit politics in May 2015 after the Alberta N-D-P swept the Progressive Conservatives from power.
Prime Minister Justin Trudeau says Prentice brought deep convictions to everything he did, whether it was in the law, business, or politics.
