"Green Levy" lightened by the elimination of the HVT

An addendum to yesterday's post. Down at the bottom of the section on the Green Levy (in Appendix 5 of the budget document), it says this:

With the introduction of the new levy, the existing excise tax on heavy vehicles will be eliminated effective March 20, 2007

What is this "heavy vehicle tax"? I looked all over the GC web site, without much luck. But this article in the Star says:

the impact of the penalty will be reduced, because the budget states that Ottawa will drop its excise tax on heavy vehicles, which typically adds $500 to $700 to the cost of a big luxury car or full-size SUV.

So, it's even less of a penalty than it sounds.
