This is something the European Union just announced they were signing last week. It was under negotiation for several years. The WHO Framework Convention on Tobacco Control is an international treaty. In the same way the Kyoto protocol applies to climate change, this applies to tobacco. Canada was a leader in the original negotiations between 2000 and 2003. Of course, Canada has been a leader in tobacco control globally for some time. Because contraband itself is an inherently international issue, parties felt this was a tool that might be able to assist.
Among the measures in there are ones for tracking and tracing. There's an obligation on parties to document the roots of where tobacco came from, for it to be marked, and to document where it is going, and where it is diverted, in the same way a Purolator package might be tracked at different stages of distribution. There are different timeframes for implementation.
There are other obligations with respect to international cooperation, with respect to licensing, and so on. The Canadian delegation feels this is very feasible for Canada to implement.
