Just to inform the discussion regarding Cabinet Confidentiality, sinc eI've seen people talking about 'well why don't the RCMP get court orders' and such- the applicable section of law is
section 39 of the Canada Evidence Act.This is one of the most cut and dried sections of any law in Canada, and it doesn't offer a legal or judicial mechanism to get around it, as are found with other similar evidentiary exclusions such as those found in sections 37 or 38 relating to public interest, national security, or diplomatic relations.
There is literally no power whatsoever for any judge of any court at any level to override cabinet confidentiality. Ministers of the Crown and the clerk of the Privy Council have an absolute power to withhold cabinet confidences from disclosure. There is no mechanism anywhere that lets police, courts, or any other public body compel the disclosure of cabinet privileged information.
