What is the current state of the law on disclosure of confidential information?

In R. v. Toronto Star Newspapers, supra, at para. 28, Doherty J.A. indicated that caution is required in editing contents of an information to avoid disclosure of the identity of a confidential informant. He instructed that: [page256] if there is any doubt as to whether disclosure would reveal that identity, disclosure should not be made. In some cases, blanket non-disclosure is required, since it cannot be said with any confidence that disclosure of any kind would not run the risk of revealing the identity of the informant: R v. Leipert, 1997 CanLII 367 (SCC), [1997] 1 S.C.R. 281, 112 C.C.C. (3d) 385.
