OTTAWA — Canada’s spy chief backs the Conservative government’s troubled bid to bolster Internet surveillance powers, and has offered to help tweak the legislation to make it more palatable to a wary public.

In a letter to Public Safety Minister Vic Toews, Canadian Security Intelligence Service director Dick Fadden says the spy agency was “extremely pleased” to see the bill come before Parliament, considering it “vital” to protecting national security.

CSIS was drafting “potential options” to strengthen accountability measures in the bill, says the late February letter, sent to the embattled minister following a wave of opposition to the legislation from civil libertarians and Internet privacy advocates.

The Canadian Press obtained a declassified version of the top secret letter this week under the Access to Information Act.

The federal legislation would allow police, intelligence and competition bureau officers access to Internet subscriber information — including name, address, telephone number, email address and Internet Protocol address — without a warrant. An IP address is the numeric label assigned to a computer on the Internet.

It would also require telecommunication service providers to have the technical capability to enable police and spies to intercept messages and conversations.
