Books, children’s clothing, diapers, and newspaper subscriptions are among the products Ontario has exempted from the 8 per cent provincial component of the 13 per cent harmonized sales tax that will be implemented next July. And as of Thursday, a new kind of purchase will added to the list: cheap fast food. Finance officials plan to announce the exemption of fast food items under $4 at a Toronto Tim Hortons. Ontario Finance Minister Dwight Duncan and Revenue Minister John Wilkonson say the new tax scheme will create an estimated 591,000 new jobs in Ontario. Opposition parties dismiss the HST as a tax grab.
