Judge blasts CSIS for not revealing secret program that has been illegally keeping metadata since 2006

TORONTO — A previously unknown unit of Canada’s intelligence service has been illegally keeping data unrelated to national security threats, the Federal Court disclosed Thursday.

In a hard-hitting ruling that was partly blacked out, Justice Simon Noel rebuked the Canadian Security Intelligence Service for not telling the court about a secret metadata program launched in 2006.

The Operational Data Analysis Centre was unknown even to the judges who had been issuing the warrants to collect the information it mined, according to Noel’s ruling.
