The KGB was concerned that the FLQ's attacks could be linked to the Soviet Union.

It designed a disinformation campaign and forged documents to portray the FLQ as a CIA false flag operation. A photocopy of the forged "CIA document" was "leaked" to the "Montreal Star" in September 1971. The operation was so successful that Canada's prime minister believed that the CIA had conducted operations in Canada. The story was still quoted in the 1990s, even among academic authors.

The Front de libération du Québec (FLQ; "Quebec Liberation Front") was a separatist and Marxist-leninist paramilitary group in Quebec.
