The man who was given CPR at the Canmore Lake incident was identified. The 28-year old, Kyu-Heon Sim was a friendly, good-hearted man and easy with a smile.
Unforeseen loss
Employed as a supervisor at the Calgary Leon’s store, Sim was spending his day off swimming at Canmore’s Quarry Lake when local emergency crews received calls about a swimmer in distress.

Calling to bystanders for help, he slipped beneath the surface of the water before rescuers were able to reach him.
He was found unresponsive soon after and CPR was started as EMS arrived on scene. Sadly, he was declared dead after he was rushed to a hospital.
Bystander action
