What is the Canadian Courts’ role in reviewing decisions by provincial oversight authorities?

The role of the courts in reviewing decisions of provincial oversight authorities (like Privacy Commissioners) is one of judicial review. This is not a re-trial of the entire case. Instead, courts apply a standard of review to determine if the authority made a reviewable error. Such errors include errors of law, like misinterpreting a key term in the governing statute, or making a decision that is patently unreasonable based on the facts and law.

A. Courts review the authority's record and decision, not all underlying investigative notes, unless it is relevant to the specific error being alleged on review.
B. The ability to impose sentences for offences under privacy acts is a separate quasi-criminal proceeding, not the typical function of a judicial review of a commissioner's findings.
D. While decisions from other jurisdictions may be considered persuasive, the court's primary role is to assess the legality and reasonableness of the specific decision before it, not to conduct a comparative analysis.
