It is through the Minister of Public Safety. The way the act spells it out, it gives the minister the ultimate decision-making authority on whether there is a national security concern. He makes the decision on the “will be” and the “could be” that I mentioned in the two different phases, but it's obviously heavily reliant on the analysis of both the security and the intelligence community, who report to the Minister of Public Safety.
If he makes a recommendation, that would be taken with extraordinary seriousness by the Minister of Industry.
