A federal review agency says sensitive information gathered by the Canadian Security Intelligence Service could be abused by Canada's allies due to lax sharing policies.

The report underscores the fact CSIS is collaborating ever more closely with Communications Security Establishment Canada, which has come under scrutiny lately due to its participation in the international Five Eyes alliance.

The American NSA has been the subject of almost daily headlines due to leaks from former contractor Edward Snowden that have revealed the agency's vast surveillance of worldwide communications.
In its report, tabled in Parliament, the Security Intelligence Review Committee recommends CSIS develop clearer and more robust principles of co-operation with CSEC to ensure appropriate information sharing.
