The federal government won't be calling an inquiry into the Air India investigation, at least not before the trial is over.

Solicitor General Wayne Easter said during question period on Monday that he wouldn't comment on allegations that the Canadian Security Intelligence Service knew about the Air India bombs ahead of time – except to reject them.

"Protecting Canada and Canadians from acts of terrorism has been a primary mandate of CSIS since its inception in 1984," Easter said. "To suggest that CSIS for any reason would pull back from an ongoing counter-terrorism investigation and jeopardize the lives of Canadians and others is absolutely absurd."

Documents released late last week indicated that the spy agency had a mole inside the Sikh separatist movement allegedly behind the two June 1985 bombings that killed 331 people.

Air India Flight 182 exploded over the Atlantic, killing everyone on board. Hours earlier, two baggage handlers died in an explosion at Tokyo's Narita Airport.

Over the weekend, allegations emerged that a CSIS mole, placed deep inside the conspiracy, had been pulled out days before the attack.

Worse, the spy agency is accused of failing to warn police of the impending attack, and then obstructing the investigation, including destroying evidence.

Hours of wiretap evidence were destroyed following the bombings.

"Will the solicitor general immediately initiate a full public inquiry to ensure there was full disclosure on the part of CSIS?" asked Canadian Alliance MP Kevin Sorenson.

"This has been the longest, most costly investigation in Canadian history and my interest and Canadians' interest is to see it carried out through to its conclusion in court," Easter said. "I won't jeopardize the case by making comments that would be misconstrued."

Two men, Ripudaman Singh Malik and Ajaib Singh Bagri, are currently on trial for the bombings, facing charges of murder and conspiracy. Another, Inderjit Singh Reyat, is serving a five-year sentence after pleading guilty to manslaughter.
