Thank you for that question. I know it's a really good one because we get it often.
What I would suggest is that we do a really good job in terms of assessing the risks, either known or unknown, that we would be facing at any given time. We rely upon a number of factors that influence our definitions and our determinations of risk, and those relate to the systems we use, whether it be one of our own business rules and applications or whether it be through our national targeting sector, which enables us, as a result of early receipt of information, to determine what may or may not be coming our way.
In addition to that, we work with our law enforcement partners, nationally, federally or locally, in addition to the intelligence professionals who work with us at the CBSA. In that instance, it allows us to notify our front-line operation if there are risks or threats coming our way, and we can plan accordingly.
At the same time, our front-line operations have the opportunity to randomly select and make referrals for more detailed reviews as part of our secondary operations. For the most part, however, we reserve those for the most high-risk situations, so that we cannot and do not impede the free flow of low-risk traffic and goods into the country.
