Does solicitor-client privilege extend beyond litigation privilege?

Solicitor-client privilege is a class privilege which never ends, unless waived or unless the communication is in furtherance of[page680] a crime. Litigation privilege ends with the litigation. As stated by Fish J. in Blank v. Canada (Minister of Justice), 2006 SCC 39 (CanLII), [2006] 2 S.C.R. 319, [2006] S.C.J. No. 39, at para. 37 ("Blank"): Thus, the principle "once privileged, always privileged", so vital to the solicitor-client privilege, is foreign to the litigation privilege. The litigation privilege, unlike the solicitor-client privilege, is neither absolute in scope nor permanent in duration.
