The two other areas in which it happens in Bill C-31 are the designation of countries as safe and the designation by the minister of people as so-called irregular arrivals. It's important to know that these instruments are not actually covered by the Statutory Instruments Act, so they are not subject either to parliamentary oversight or even to the process for regulatory rule-making by cabinet. This causes actual concerns about democratic legitimacy. What it does is it gives a minister the power to make law. That's different from a power to exercise discretion. It's actually a power to make binding rules, and sometimes rules which, it turns out, are inconsistent with regulation, and possibly, arguably, on occasion, inconsistent with legislation.
Quite apart from what you'd take to be the merits of the content of any instruction, I'd suggest to you that the practice of ministerial instruction itself, from a democratic perspective, from a parliamentary legislation perspective, is on shaky legal ground.
