The University of Ottawa's Sigma Chi Fraternity braved the cold Monday for their Homeless for the Homeless event.
Students set up a tent on the university campus to find out what it's like to sleep outdoors in the winter.
They'll be staying outside for 72 hours straight.
Fraternity member Alejandro Orozco tells CFRA the event shocks people who see them camping out for charity.
"When we have our comfy homes and blankets, there are people outside in February," Orozco says. "Ottawa is renowned for its cold and I can't even believe that people have to sleep outside, so we try to raise awareness by sleeping outside and doing exactly what you don't want to do, just so someone else doesn't have to."
Sigma Chi members hope to raise $3,000 for the Ottawa Mission.
