By its nature, the contraband problem is hard to measure and to quantify, but on the example you mentioned, there are examples of products that have federal tax paid but not provincial tax, and it's supposedly for sale on a first nations reserve, but then it gets diverted off reserve. It has the stamp on it, it has the health warning on it, and either people come on the reserve to buy it or it's diverted for distribution into formal channels off reserve. That is an example of the different categories of contraband.
We do need a comprehensive strategy, as you indicate.
