NATO 'not shaken' by Canadian spy allegations

A high-ranking U.S. military official says the case of Sub-Lt. Jeffrey Paul Delisle, the Halifax naval officer accused of spying, has not diminished NATO's faith in Canada.

"I will tell you as a member of a military that is one of Canada's strongest allies and partners, we're not shaken by this at all and I don't think our strategic imperative has been diminished in any way, shape or form," Vice Admiral David Busse told reporters Tuesday. He is in Halifax attending the 2012 Maritime Security Conference.

Canada's Rear Admiral David Gardam called the Delisle case "regrettable."

But Buss said the U.S. has "blips" too. He said all sides must learn from the case because they must continue to share information.

Delisle, 41, faces two charges of violating a section of the Security of Information Act and one charge of breach of trust under the Criminal Code.

He is accused of passing secrets to a foreign entity or terrorist group sometime between July 2007 and Jan. 13, 2012.

Delisle was working at Trinity, a secure naval intelligence centre in Halifax, when he was arrested on Jan. 14. He has been in custody ever since.

The case against Delisle is due to return to court this month.
