Thank you to my colleague for his question to help me clarify.
As I stated, there are three levels of notification that we provide to air operators. First is information. Second is recommendations. The third is a ban.
In fact, I can say that the newly formed office recently issued a NOTAM over certain parts of Ukraine because of the rising military tension at that border. We've seen the results of this office take effect in the issuance of a ban for Canadian operators. They are not to travel over that region.
