A million years ago … pardon me, my notes indicate rather surprisingly that it was the spring of 2021. Two and a half years ago, the Supreme Court found in favour of the federal government in the case of the References re Greenhouse Gas Pollution Pricing Act (GGPPA). It was a tricky division of powers question.
Since manmade climate change is a global collective action problem, laws to curtail greenhouse gas emissions aren’t inarguably in the natural bailiwick of either the federal government or the provinces. The federal Liberals made such a law, applying a “backstop” carbon price to — IN THEORY — the federation as a whole.
