"Brett received CPR on site and was taken to a local hospital by ambulance where he was treated. He was then transported via an air ambulance to University Hospital in London, Ontario where he was admitted to the cardiac ICU.
"Our thoughts and prayers are with Brett and his family," Maloney continued. "We request that everyone please respect their privacy at this time. We will provide an update on Brett's status when information is available."
