A Canadian intelligence officer who sold secrets to Russia has apologized to his children and family, saying he is sorry for the pain he caused them.

Sub-Lt. Jeffrey Paul Delisle offered the apology just before his sentencing hearing in Halifax provincial court ended Friday. Delisle pleaded guilty in October to espionage for selling secrets to Russia in exchange for nearly $72,000.

The judge has reserved a sentencing decision until next Friday. The prosecution is seeking a sentence of at least 20 years in prison. Delisle's lawyer says he should be given a sentence of nine to 10 years.

Delisle worked at a naval intelligence center and had access to information shared by Canada, the United States, Britain, Australia and New Zealand.
