In Canada (Privacy Commissioner) v. Blood Tribe Department of Health, 2008 SCC 44, the force is the Personal Information Protection of Electronic Documents Act ("PIPEDA") and the object is solicitor-client privilege.  Section 12 of PIPEDA grants the Privacy Commissioner express statutory power to compel a person to produce any records that the Privacy Commissioner considers necessary to investigate a complaint “in the same manner and to the same extent as a superior court of record”.  The issue in Blood Tribe was whether this conferred a right of access to documents protected by solicitor-client privilege.  The Court held unanimously that the broad grant did not contain the requisite specific express authority to override privilege.

The Court stated the rule that "general words of a statutory grant of authority to an office holder such as an ombudsperson or a regulator do not confer a right to access solicitor-client documents, even for the limited purpose of determining whether the privilege is properly claimed.  That role is reserved to the courts.  Express words are necessary to permit a regulator or other statutory official to “pierce” the privilege." 

The Court also noted that "while the solicitor-client privilege may have started life as a rule of evidence, it is now unquestionably a rule of substance applicable to all interactions between a client and his or her lawyer when the lawyer is engaged in providing legal advice or otherwise acting as a lawyer rather than as a business counsellor or in some other non-legal capacity."

Speaking of the Supreme Court of Canada, the law you're looking for just might be in the "unreported judgments" section of the Supreme Court's user-friendly website.  How does a Supreme Court decision go unreported?

Have a great day,
