The son of Peter Nygard, a former fashion mogul who had been found guilty of four counts of sexual assault, told media on Sunday that he was glad his father had been brought to justice, calling him a 鈥渟ystematic monster.鈥�

Kai Zen Bickle, who goes by his mother's surname, explained that he felt 鈥淜ai Nygard鈥� had died four years ago, when he said he witnessed his father 鈥渂asically assault a young child鈥� at a dinner party.

At the time, Bickle spoke up to executives at his father鈥檚 company, where he also worked.

鈥淚 was attacked and told that I was mentally unwell and all of these things, and I got a taste of what it鈥檚 like to blow the whistle against 鈥� a powerful predator,鈥� he said Sunday.

Nygard 鈥渦sed his business talents for evil, to prey on others,鈥� Bickle said.

鈥淎nd it鈥檚 a very good thing that justice was served here.鈥�

The 82-year-old Nygard, who has been the subject of numerous sexual assault allegations in both the U.S. and Canada, but was acquitted of a fifth count, plus a count of forcible confinement.

The charges stemmed from five women who testified that various meetings with Nygard, ranging from tours to job interviews, ended with them being sexually assaulted by him at his company鈥檚 headquarters in Toronto. The allegations dated back from the 1980s until the mid-2000s, and Nygard denied all five women鈥檚 allegations.

One woman testified that she was only 16 years old at the time of the assault.

Bickle said on Sunday that he is thinking about 鈥渁ll of those who care about justice and are open to the idea of stopping predators from abusing and targeting children, using drugs to abuse women, and using tactics like jurisdiction loopholes or threats of lawsuit to silence their victims.鈥�

He had flown in to watch his father take the stand during the trial earlier this fall.

Prior to that moment in court, the last time he saw his father in person was 鈥渢he 2019 dinner, where I saw him inappropriately touch a child. And I said something then, and I was attacked for that internally within the company, and silenced, told that I was crazy.

鈥淪ince then, it鈥檚 been a massive effort to seek justice.鈥�

Speaking against his father came at a cost, he said, tarring him professionally and personally.

鈥淚t鈥檚 not a good brand association to be the son of a monster,鈥� he said. 鈥淚t鈥檚 negatively impacted me all across the board. I lost everything, I walked away from an inheritance to do the right thing.鈥�

The upside, Bickle said, is being safe in the knowledge that 鈥渙ne more child won鈥檛 be affected, one more woman won鈥檛 be affected, and that he has to now sit and think about what he鈥檚 done.

鈥淚 loved my father,鈥� he continued. 鈥淚t hurts me to see all of these things. I knew a different man. I got a different version of him. And for me that bond was real, those moments were real.鈥�

He credits his mother with giving him the strength to come forward and stand up for his principles. Bickle, who is a dual U.S.-Canadian citizen, grew up in the Washington statewith his mother, and only began to spend more time with his father as he got older.

Nygard rose to prominence in the fashion world after he founded a fashion company in Winnipeg in 1967 that produced women鈥檚 clothing. He stepped down as chairman of the company in February 2020 after the FBI raided his offices in New York City.

Nygard is still facing criminal charges in three other jurisdictions, including sexual assault and forcible confinement charges in Quebec and Manitoba, and nine counts in New York City, including sex trafficking. These charges haven鈥檛 been tested in court. Two of Nygard's other sons have also filed sexual assault charges against their father.

On Sunday, Bickle said he 鈥渓ocked eyes鈥� with his father in the courtroom after he was found guilty.

鈥淔or me, it was emotional, but again I鈥檇 like to stress there are so many survivors out there who鈥攖his is their day.鈥�

Since he became aware of his father鈥檚 criminal behaviour, Bickle has been working to find ways to close legislative loopholes that allow predators to escape consequences. That work is far from over, he says.

鈥淚t鈥檚 not just about Peter Nygard, it鈥檚 about examining the system, the laws and the rules, to see where that problem was so that we can correct it for others in the future,鈥� he said. 鈥淭hat鈥檚 where we鈥檒l actually get a big benefit from this tragic and terrible situation.鈥�
