That's an interesting question. Federalism is not only a challenge for Canada. Germany is a federation within the EU, which is also a complex challenge. This is a framework law, so we're not looking at prescribing policy; what it does is lay down a foundation, a process, so that the government can organize a transition—its inevitable transition toward decarbonization.
We have in Canada a model of co-operative federalism. We have Supreme Court judgments that have carefully laid out, through legal doctrines, that the pith and substance of legislation really determines its constitutionality. There are always incidental effects on different jurisdictions—it's inevitable—but we have a long history.
Back in 1887, the Privy Council ruled that the provincial tax on banks was in fact constitutional because it was not an attempt to regulate banks, but simply an effort to raise revenue for the provinces. I think we have to take into consideration that every national law is adopted within a certain legal culture. We have a strong legal culture of co-operative federalism in Canada that can ensure there is a spirit of co-operation.
During COVID, we saw a team Canada approach, and we saw federal discretionary transfers to the provinces, so we know that in fact the federal government and the provinces can co-operate very tightly when it comes to public health crises, and this is the public health crisis of our lifetimes.
