If you listen to the (Toronto) media, the equalization deal for NL and NS is unfair to Ontario. If you instead investigate the whole point, you'll discover that, under the equalization formula, Alberta's oil revenues are NOT considered on the plus side. Therefore, if oil revenues aren't considered for Alberta, why should they be considered for anyone else? The logical extension of this is, all non-renewable resources should be treated the same way, so, for example, all mining royalties should be deducted from the formula.
Now back to cars.
