Dwayne Louis Simard, one of the three men arrested in a weekend standoff in Winnipeg, has died in Stony Mountain prison.
Correctional Service Canada said Simard, 37, died on Monday, but it did not elaborate on the circumstances of his death, which is under investigation.

Simard had been sentenced to two years and eight months for aggravated assault, which he began serving in November 2017. He was released in early September 2019, but two weeks later breached his conditions, police said at the time.
He was arrested on Saturday along with two other men following an hours-long standoff at a home on the 600 block of McGee Street.
Winnipeg Police Service Const. Jay Murray told reporters Sunday that officers arrived at the house to execute a pair of entry warrants shortly after 11 a.m. Saturday.
It was believed two men who had outstanding arrest warrants were in the residence, Murray said, including Jesse James Daher, who is facing a charge of second-degree murder in the early October death of Mohamed Mohiadin Ahmed.
Terry Ryan Monkman, 37, was reportedly taken into custody without incident. Daher, 28, surrendered to police at 6:40 p.m. Saturday. Ten minutes later, Simard exited the residence. All three were arrested and charged with weapons offences.
