The proposed changes would take effect July 1, 2010. The HST @ 13% would replace the GST @ 5%. Since you pay only provincial taxes on a used car, I don't see how they are going to separate them, so you'll pay 13% I assume. There is very little good info on the web about it.
You will pay on new houses (with rebates on houses less than ~$500K) and groceries, books, a bunch of other shit.
Businesses can claim back the HST instead of just GST (but don't they claim the PST separately) so they say businesses will have more rebates.
Just a ****ing tax increase. Call a spade a spade.
