Medicine Hat–Cardston–Warner MP Jim Hillyer was found dead in his office in Ottawa early this morning.
Hillyer, 41, had reportedly not been feeling well as of Tuesday evening.
The state broadcaster claims that his family had contacted Parliament Hill security when they were unable to contact him.
"Jim was a valued and hardworking member of the Conservative team, and a passionate advocate for those he represented," Interim Conservative Party Leader Rona Ambrose said in a statement.
"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," Ambrose added.
Hillyer was first elected in 2011 and was re-elected in 2015. He had previously survived a battle with cancer in 2003.
