Boxing Ontario didn't properly investigate alleged abuse by Ottawa coach, boxer says

Kaitlyn Clark doesn't remember much about the 2017 national boxing championship. She does remember feeling so weak she could barely fight her opponent inside the ring. 

In the days leading up to the match in Quebec City, the boxer said she spent every waking moment trying to lose the more than 10 pounds necessary to make her weight class.

Clark said she stopped eating and submerged in a hot bath for hours to sweat out as much water weight as possible. At one point, she recalled losing consciousness.

"I have never felt so close to death in my life," Clark would later write about that experience.

On the day of her weigh-in, she made sure her hair was bone dry and stepped onto the scale naked. She barely made it under the maximum 64 kilograms, or 141 pounds, to qualify in the "light welterweight" category for elite female boxers.

"I was completely pale. I looked horrible," Clark said, referring to photos she later saw of herself after the fight, which she lost in three rounds. People who watched told her the fight was a disaster. 

Clark would win a national championship two years later, but not before this moment she calls rock-bottom — a place she says she was forced into by former coach Jill Perry.

From 2011 to 2017, Clark said she felt "controlled and helpless" while training under Perry at Beaver Boxing in Ottawa. Clark said she experienced harassment, psychological abuse and grooming and was immersed in an environment that led to an eating disorder, suicidal ideation and an Olympic-track boxing career being placed on hold indefinitely.

Now 30, Clark has filed a formal complaint against Perry to Boxing Ontario, which oversees 150 clubs across the province. CBC News has seen a copy of the complaint and dozens of emails,
