A 55-year-old man found unconscious near an alley in Winnipeg's Exchange District on Wednesday has died.

A passerby found the man at about 5:30 a.m., near the United Way building at Main Street and Alexander Avenue.

He was rushed to hospital in critical condition where he was later pronounced dead.

Police said there were no obvious signs of foul play, though an autopsy must still be performed.

The man had been outside for a number of hours and weather was likely a factor in his death, police said.

The temperature outside at the time he was found was –15 C with a windchill making it feel more like –24.

The man's identity will not be released to the public, police said.

The death has shocked people at the Lighthouse Mission, another shelter nearby.

Cassie Caribou, who was lined up Wednesday with other people waiting for boots the shelter was handing out, said she has spent the night outside in the cold, too.

"It sucks," she said. "It's not all that fun. But you got to do what you got to do to survive."

Caribou wonders why the man didn't seek help at the Lighthouse Mission.

"There's lots of beds, there's mats for under minus 20," she said. "So, if anybody needs any shelter or anything, they can come here."
