To get specifics on that, you might get a better answer from IRCC, but what I believe I was referring in the interview was the rapid ramp-up at the embassy here in Warsaw. We haven't had a visa program for Poles going to Canada since 2008. I feel that we were very quick. IRCC responded incredibly fast and we had support.
Right now, for example, we have 29 temporary duty staff here from IRCC, from across Canada and other missions in the region, helping exactly with getting the Ukrainians who are applying for visas to go to Canada. If you're in one of six countries in the region, you can get your visa very quickly. If you are outside those six countries, it takes a bit longer, but everything is flowing as quickly as it possibly can.
I'm not sure what to say about the use in other circumstances. I'm sorry. I can take note of your question, though, and I can reach out to IRCC to get more information on that.
