Yes. I believe you are referring to an authority under section 22.1 of our legislation that we commonly refer to as the “negative discretion” authority of our minister. That provides our minister with the ability to look at a range of public policy considerations and, as you said, declare that a foreign national may not become a temporary resident for a period of up to three years.
In addition to our legislative authority, we do have guidelines that are available on our website. They refer to activities or behaviours that could attract the attention of our minister. Under those guidelines, we have three types of activities listed. The first would be individuals who are promoting criminal or other terrorist activity. The second section, which I believe you are referring to, would be foreign nationals from sanctioned countries or corrupt foreign officials. The last category would be foreign nationals who may pose a public health risk to Canada.
