Richard Henry Bain, 61, appeared at a Montreal court to face charges of first degree murder and attempted murder, but the proceedings were quickly adjourned to December 7.
The judge agreed to a defense request to have all of the relevant court documents translated into English, from French.
Bain's lawyer, Elfriede Duclervil, also pressed for the prosecution to hand over outstanding evidence for review, including a full transcript of a 38-minute interview Bain gave from prison to English-language radio station CJAD following his arrest.
The radio station played only parts of the interview in which Bain said he was delivering a message from God and called for the island of Montreal to split from the rest of the province because the ruling Parti Quebecois looked to split Quebec from the rest of Canada.
Bain, the English-speaking owner of a hunting and fishing business, is alleged to have opened fire on September 4 outside a Montreal concert venue where Quebec's premier-elect Pauline Marois was celebrating her separatist Parti Quebecois' victory in provincial elections.
A lighting technician was killed and another hall worker wounded before the shooter, dressed in a balaclava and bathrobe and shouting "The English are rising," was subdued by a police officer.
Duclervil also said she would ask for an immediate investigation of an incident that resulted in Bain showing up at a courthouse with a small cut on his forehead, claiming "a guard pushed me."
She said she has not yet decided whether to ask for a psychiatric evaluation of her client.
