There are two parts to the answer.
First, in this case, it was a small plane. It was a commercial plane, but smaller than a Boeing 737. When we were informed that it might be subject to sanctions, we notified Transport Canada, which took over the file on the aircraft.
As for the passengers, our role was to determine whether they had all the necessary documents to be allowed to enter the country. I should point out that there is no ban on Russians entering the country at the moment. So their eligibility is assessed on the basis of their background and the documents and visas they need. If someone has to leave the country, we make sure that our officers follow up.
In a case like Yellowknife, for example, passengers who would be denied entry would be redirected to Calgary or Toronto, perhaps, to leave the country, and we would confirm their departure to ensure that they have indeed left the country.
