A carbon tax in Ontario is coming.

Opponents of a carbon tax in Ontario, especially those holding elected office, are in a pretty sweet spot right now. Simply put, there will be a carbon tax in Ontario come the first of January, 2019, and they can blame someone else for it. So, if it is a dismal failure, they win, big.

A carbon tax that jacks up government revenues and increases spending on ministerial pet projects will be a failure, let's be clear on that. Especially if it doesn't measurably reduce emissions, or even just reduces them by a lower amount than forecast. If those things happen, the tax will be a talking point bonanza for opponents.

If the tax works, though, opponents will still have lots to fuss about. If the tax reduces emissions while also not funding pet projects and new bureaucracy (green car subsidies anyone?), it still won't be perfect. Taxes never are. Policy never is. Everything is a compromise and that leaves even very good policy open to criticism, partisan or otherwise.

In a bold new carbon tax-inclusive world, potential cash grabs by new governments and ongoing rate hikes will be two headliners in future debates, especially since no one is absolutely sure what tax level will deliver the emission reductions we are seeking. There are also income redistribution effects to talk about: who pays the tax and how much of their income does it eat up? Who gets the benefits of reductions in taxes elsewhere to keep the overall impact "revenue-neutral?"

The lack of a sunset clause can also be debated. Let's all recall, the income tax was originally very low and temporary. If we save the planet, will we still keep paying the tax? I suspect we all know the answer to that: of course, we will. So the tax will be a political gift that keeps on giving to opponents for years to come.

If the opponents of a carbon tax are sitting pretty, politically speaking anyway, what about the proponents?

Well, they are likely to be pretty happy, too. The tax is coming after all, and there is probably very little that Premier Doug Ford and his allies in other provinces can do about it.

I say probably since this whole national carbon tax "backstop" is heading for the courts and, as any truly good lawyer will tell you, once you are in front of a judge it's 50/50 pick 'em every day of the week.

That said, an unpredictable judiciary isn't the...
