Jeffrey Delisle's sentencing hearing was a "he said, she said" over how much damage the former naval intelligence officer caused by selling secrets to the Russians.

The Crown argued Delisle compromised the safety of Canadian intelligence assets and damaged relationships with our closest allies.

"We may be cut off from certain intelligence," Michelle Tessier of the Canadian Security Intelligence Service said.

The defence countered with Wesley Wark, an intelligence and security expert. Wark said there's no way to know how much damage Delisle caused — or if there will be "real-world consequences."

"Government agencies, when they don't have the details, will engage in what's called worst-case analysis," Wark testified.
