Illinois state police confirmed that SylvainBergeron, 42, was stopped by police last Friday for a traffic violation on Interstate 355, outside Chicago.
Bergeron is an employee at Stanstead College in Quebec's Eastern Townships. The private boarding school in Stanstead educates students in Grades 7 to 12.
The Herald News, based in Joliet, IL, reported that when troopers stopped Bergeron, they found about $1.2 million worth of cocaine in his SUV.
Charles Telkie, a spokesman for the state attorney's office, confirmed that Bergeron was charged with unlawful possession of a controlled substance with intent to deliver.
Telkie would only confirm that more than 900 grams of cocaine was found in the vehicle, which is the minimum amount referred to in the criminal charge.
Bergeron could face anywhere from six to 30 years in prison with no probation.
'A diligent and loyal employee'
Staff at Stanstead College said they were shocked by the news about their colleague, who has been suspended from his duties without pay.
College spokesman Ross Murray said Bergeron has been working at the college since 2006.
"We're all very surprised. Mr. Bergeron is a diligent and loyal employee. He was very responsible and there's been no incidents in the past that would raise concern for us as employers," Murray said.
Bergeron's next court appearance is scheduled for Feb. 3.
