Sir, just to build on what has already been said, I think following ratification of the convention, Canada will have an international legal obligation to destroy stockpiles. The convention doesn't require that to be translated into domestic law of Canada. I would note that the amendment isn't necessary, as the Canadian Forces is already in the process of destroying its munitions. It's expected that this will take place well before the eight-year deadline. In fact, the remaining stockpiles that Canada has have been removed from operational stockpiles since 2007, so there's no concern that they will be used. There's certainly already a well-entrenched process for contracting out for the destruction of those stockpiles.
On December 3rd, 2013. See this statement in context.
