Former Norbourg CEO Vincent Lacroix pleaded guilty Monday in Quebec Superior Court to more than 200 fraud charges.
He was immediately taken into custody.
The fraud trial by jury will continue for his five co-accused, the court said.
Lacroix had already begun serving a prison term for securities law violations after he was convicted in 2007. That sentence was reduced, and he was set to get full parole on September 27.
He was charged with the violations after more than $100 million disappeared from his investment firm.
Lacroix is scheduled to return to court on September 25, for sentencing arguments.
