From CBC News:
Alberta MP Jim Hillyer has died in Ottawa.
The Conservative, who represented the riding of Medicine Hat–Cardston–Warner, complained Tuesday of feeling ill. He was found in his office early Wednesday morning.
Sources told CBC News his family contacted Parliament Hill security when they were unable to reach him.
In a statement, interim Conservative Leader Rona Ambrose said she was deeply saddened to learn of his death.
"Jim was a valued and hardworking member of the Conservative team, and a passionate advocate for those he represented," the statement said.
"More than that, he was a dedicated husband and father, and a man of strong faith and conviction. I pray that his and his family's faith will help them through this very difficult time."
Hillyer was first elected in 2011 and was re-elected in 2015 with 69 per cent of the vote.
He previously survived a battle with leukemia in 2003.
Hillyer is survived by his wife Livi. The couple has four children: London, Taylor, Nation and Asia.
He was 41.
