What is the standard of review for a decision-maker to grant a judicial review?

The applicant did not indicate what he believed the appropriate standard of review to be. However, his main allegation was that the decision-maker had not allowed him to address his concerns, which, the applicant claimed, constituted a breach of the principles of natural justice. When an allegation is made that the principles of procedural fairness have been breached, the standard of review is the standard of correctness (Mission Institution v. Khela, 2014 SCC 24, [2014] 1 SCR 502). Thus, the judge providing judicial review is not required to show deference to the impugned decision.
