Mr. Chair, let me start by saying what I mentioned earlier, that IRCC is the first line of defence, where we are doing the initial security screening. Based on the risk indicators, we ask the questions. We also have the biometrics availability. We work with our security partners to see what kind of pinging we get from the different databases. We also look at our own databases. Has this person used a different name or alias or different passport? This is all part of the common platform where we begin with the temporary resident visa.
If there is any indication or any flag, we refer it for a comprehensive security screening, which takes place with the CBSA and CSIS. As the IRCC office, we can only make an admissibility decision once the officer is satisfied, after consultation with our security partners, that there is a favourable return on the security flag or the advance security or comprehensive security screening. If there is not, then we will call it non-admissible and the person will not be allowed to enter into Canada.
As my colleague Ted explained earlier, there are different risk indicators that our security partners work through in terms of their association with different governments and different regimes. That part is actually worked through by our security partners. If it is not available to us or if it is inconclusive, it takes a bit more time before that security or admissibility is actually passed and the person is granted the visa.
I don't know, Ted, if you want to add anything to that one.
