Richard Henry Bain will face 15 charges including first-degree murder.
Details of his preliminary hearing had been placed under a publication ban — and, while many criminal suspects request such a ban, in this case Bain had vigorously resisted one.
The 62-year-old Bain is accused of killing one man at the exit of the nightclub where the Parti Quebecois was celebrating its provincial election win last September.
Premier Pauline Marois was making her speech during the attack. She has since said she believes she was the intended target of a political attack.
Bain will return to court on Sept. 3, one day before the one-year anniversary of the shooting. That's when a date will be set for jury selection.
Bain originally faced 16 charges but the prosecution has since revised the number to 15, including three of attempted murder.
One of those three alleges Bain attempted to murder 14 people. The list of 14 people does not include Marois.
