I'd be happy to do that.
As my colleague said, there are a number of additional pieces of information that we can request. One thing that wasn't said in her answer in English that I would add is that we can also ask for interviews. If there are risk indicators, we can request police certificates. I didn't want to minimize their importance, but I also didn't want to digress as your Conservative colleagues have done. If additional information is needed, there are a number of ways to proceed.
Biometrics is also a very important component. This is a rather new practice, historically speaking, for screening people who come here to Canada. It's very reliable. It's not perfect, but we verify that data by comparing it with the databases of IRCC and our security partners, whether in Canada or abroad.
That may not be the most reliable interpretation of my colleague's answer, but I did my best.
