Mr Nygard, 79, was arrested on Monday for claiming to have used his brand to lure alleged victims into his field in the Bahamas with promises of jobs in modeling and fashion.
The indictment claims he capitalized on the influence of the Nygard group, using its employees, funds and resources to recruit girls under the age of 18.
Fifty-seven women, including 18 Canadians, appear in court documents.
He is facing charges in court in Winnipeg after US officials ordered their Canadian counterparts to detain him.
The FBI raided Mr. Nygard’s New York City offices earlier this year after 10 women sued him for similar allegations.
Several women said they were only 14 or 15 years old when Mr. Nyguard injected them with drugs and alcohol in order to rape them.
The 79-year-old denies all of the allegations made against him.
He claims the allegations are fueled by a conspiracy caused by a feud with his billionaire neighbor in the Bahamas.
Other employees of the Nygard Group are also accused of using force, fraud and coercion to enlist women and girls before they are assaulted by him and others.
Nygard International started out in Winnipeg, Canada, as a sportswear manufacturer.
It now has more than 170 stores in North America.
Earlier this year, a company spokesperson said Mr. Nygard was stepping down as chairman of all companies and stepping down from his stake.
