I would like to check that information.
But what I can tell you is that there is probably nowhere in the world where there is federal taxation and a provincial distribution monopoly. That is very unique to Canada. I would be very cautious before making any generalization at all on federal excise duty in terms of any taxation rules used in unitary states.
Currently, in the United States and in a number of European countries, there are no automatic adjustment rules. Is that a good thing or a bad thing? Those are political decisions.
In the case of tobacco, for example, in recent years, all international organizations have recommended the establishment of mechanisms that allow for periodic revisions of excise duties.
As I was telling you earlier, writing that into the legislation so that it is done automatically, or using informal mechanisms are decisions made at a higher level than mine.
