Dozens of law enforcement officers braved some icy cold Calgary waters Sunday morning for charity.

But before the event could even start, firefighters had to saw through more than half a meter of ice to expose the icy-cold water of Arbour Lake in northwest Calgary.

Law enforcement officers and athletes raised $10,000 for the Special Olympics.

“Their passion and their dedication to everything they do – it just inspires you, warms your heart,” said Stephen Scott, a corrections officer at the Calgary Remand Centre.

Law enforcement officers are the largest fundraiser for the Special Olympics globally. Since the initiative began about 30 years ago, $450 million has been raised.
