It's a very small piece, to be sure. But it's also a huge precedent. Almost immediately after Prime Minister Justin Trudeau made the announcement last week, the government was fielding requests for similar carve-outs from across the country. on Tuesday, Saskatchewan made formal plans to stop paying part of the tax entirely, daring the federal government to enforce it. Meanwhile, everyone from the opposition to climate advocates have criticized the message the decision sends.

So what, exactly, are the Liberals doing to their signature policy? What's the motivation for the move? Is it practical, or panic-induced? And what's coming next?
