Well, you're speaking to a former immigration control officer, as you know. They're now called “MIOs”, I think, migration integrity officers. They're stationed overseas at departure gates of flights for Canada. There they do actual screening, mostly in terms of the legitimacy of the documents.
I did that job for two years. In Narita I prevented hundreds of people from getting on planes to Canada. I have no misgivings about that whatsoever, because those people were perfectly capable of making a refugee claim in Japan, where I happened to be stationed, and none of them did.
So in terms of measures that actually screen, I'm entirely in favour. There are resource implications, but the current cursory review of a paper application that constitutes our TRV is not, I'm saying, actual screening.
