I'm not sure if the Canada Gazette is the right vehicle to do that. The Gazette is usually used for advertising regulatory change and consulting Canadians in that way on change about to come.
Earlier on, there were amendments to ensure that NSIRA would be looking at and reviewing all ministerial directions. In the annual report of NSIRA, you would already see changes and any new ministerial directions that way. From that point of view, I'm not sure if the amendment is required.
