It's being done through a variety of means.
Primarily, we're seeing a lot of fentanyl now moving in the postal and courier modes, so we're seeing it in our postal centres. Often, in Operation Blizzard, the majority of it was probably outbound. We saw a pattern of what we call micro-traffickers sending small amounts of fentanyl south. We see it coming inbound. We also see fentanyl coming in with individual travellers. That's what our experience has been.
The challenge with fentanyl, as you probably know, is that a very small amount can be very potent in so many awful ways. It's very easy to conceal, which makes things like postal and courier the preferred modes for shipping it.
