Police were called to the scene around 8 a.m. where they found a 25 year old man in cardiac arrest. Paramedics rushed the man to the hospital in critical condition.

Soon after, he was declared dead.

"A 25 year old died today ...it's very sad," police spokesperson Louis-Philippe Bibeau said in a phone interview.
