Such as fentanyl, the synthetic opioids; it's a huge concern for us on a daily basis.
It's something we are working on with my Border Five colleagues. The Border Five is Canada, the U.S., Australia, New Zealand, and Great Britain. In fact, we just met in Sydney, Australia, to talk about how we can work more closely with the postal union and Canada Post to try to get better data in advance, so that we can target, because with that volume, it's simply impossible to keep up with the risk we're trying to mitigate. It really relies more on data.
It's less of a problem on the courier side, because we get good data analytics from companies such as FedEx and UPS, allowing us to target our efforts and manage the risk better. On the mail side, though, e-commerce is a huge problem.
