Both deaths happened on June 7, 2017, but Correctional Service Canada (CSC) officials have not said if they are connected.
Christopher Andrew Van Camp, 37, died after being found in medical distress.
Van Camp was nearing the end of a five year, five month sentence for a number of convictions including armed robbery, fraud, and break and enter.
RCMP were notified and said Van Camp’s death is being treated as suspicious.
An autopsy is scheduled for later this week.
Daniel James Tokarchuk, 44, was taken to hospital by emergency personnel early in the morning. He was pronounced dead at 4:24 a.m. CT.
Tokarchuk had been serving an indeterminate sentence since Dec. 16, 2004 for second-degree murder in the killing of Hell’s Angels associate Trevor Savoie in 2002.
He was also charged with mischief, and failing to comply with appearance notices.
Tokarchuk’s brother, Kevin, was shot in the head at his home exactly one year after Savoie’s death in a suspected revenge killing. No one was ever arrested for Kevin’s murder.
The causes of death have not been released and no other details have been provided.
Police and the coroner’s office have been notified and CSC staff will be reviewing the circumstances of the incidents.
