What privilege does solicitor privilege apply to confidential communications between solicitor and client?

The zealous protection of the privilege that attaches to communications between a client and solicitor is well established. Its scope is conveniently summarized in Descôteaux v. Mierzwinski, 1982 CanLII 22 (SCC), [1982] 1 S.C.R. 860 at 892-3: In summary, a lawyers’ client is entitled to have all communications made with a view to obtaining legal advice kept confidential. Whether communications are made to the lawyer himself or to employees and whether they deal with matters of an administrative nature such as financial means or with the actual nature of the legal problem, all information which a person must provide in order to obtain legal advice which is given in confidence for that purpose enjoys the privileges attached to confidentiality. This privilege applies to all communications within the framework of the solicitor-client relationship which arises as soon as the potential client takes the first steps, and consequently even before the formal retainer is established.
