Sure. I would just preface my comment by saying that it is a Herculean task for any government to monitor small arms and light weapons in its territory, especially when some of the territory is not controlled by its forces.
The Ukrainian government has been very aggressive in countering illicit weapons. Seizures occur on a daily basis. There is enough public information that you can see how they are doing it. They are doing it professionally. They are documenting it. They're taking down serial numbers and the information necessary for intelligence. They are destroying in situ some of the more dangerous weapons. It's obvious that they are taking this problem very seriously.
Whether they have the necessary resources to really get on top of that problem, that is a question for the Ukrainian government. That's something the Government of Canada might want to explore with them.
