It's probably different. I won't anticipate your question.
I agree with Brian. We should look at what we tax, too. One of the things to keep in mind is that if you look at the rest of the OECD, Canada ranks second last in terms of taxing pollution and waste. Most other OECD countries have begun to move their tax system and diversify what they tax. If you tax income, you're discouraging the thing you tax. You're discouraging working. You're discouraging investment. We don't want to discourage those things.
If you tax pollution and waste, you're discouraging pollution and waste. We do want to discourage those things. We should also look at what the rest of the OECD is doing, but do it in a way that is tax neutral, so that we're actually cutting other taxes as we're bringing those up. We're not increasing the net tax burden. We're just shifting towards things we want to discourage.
