A judge has scheduled three days in February to hear evidence against Benoit Roberge, who is accused of passing along secrets to the Hells Angels.
Quebec court Judge Robert Marchi will determine whether there is sufficient cause to send the ex-biker gang expert to trial.
Roberge is facing one charge of obstructing justice, one of breach of trust and two related to gangsterism.
He retired in August and had been working for the provincial tax agency. He was subsequently fired from that post following his arrest.
He has been detained since last October and has waived his right to a bail hearing until a later date.
A publication ban was placed on Thursday's discussions about the preliminary inquiry.
Roberge was not present for the hearing and was represented by his lawyer.
The inquiry will take place Feb. 19-21.
