Obviously, we work with all of our partners here in terms of looking for leads to help us target shipments that might be coming into the country. Working with the Chinese government, the RCMP had reached out a couple of years ago looking to list certain precursor chemicals.
Unfortunately, folks are fairly creative and they're looking for new ways to create this stuff all the time. My lab, which actually examines the stuff that we seize, at one point a few years ago was finding a new analog every two weeks. It's something that is, as my colleague just said, a cat and mouse game, and we're always looking for things.
We've done things with investments in terms of designated examination facilities at the ports of entry so we can get very quick analysis of something, but we continue to look for precursor chemicals. Obviously, we've had some success. In fact, in 2020, we seized 5.8 kilograms of fentanyl, which is about 2.9 million fatal doses. The seizures go up and down all the time, but with the rise of e-commerce, we're paying particular attention to that particular route.
