Now Ontario sales tax credit is administered by CRA. You don't have to apply for it. Simply check the "Are you applying GST/HST credit" on the first page of tax return, you're automatically in. The amount has been increased up to $260 per person.
今年的sales credit已经从税表上取消了.从七月份起安省将公布一个新的credit,calculated base on your family income. It would be paid apart from you tax return. So far CRA has not decided yet how much it is but only said that it would be paid out quartly.
Sorry my Chinese typing is too slow.
Plus, this new credit is called energy and property credit. This is a new form for 2010 "ON-(BEN)". It is used to calculate the credit you'll be entitle to. The threshold is increased to:single--$33000, family income under 44000.
