The federal government says Ontario can allow First Nations people to have a point of sale exemption on the harmonized sales tax.
Aboriginal people in Ontario have been exempt from the provincial sales tax for decades, and were threatening road closures during the G8/G20 summits if they didn't get an HST exemption.
The exemption though won't come into effect until this September.
Native people will still have to submit receipts to receive refunds on purchases made between July 1 and August 31.
Progressive Conservative Leader Tim Hudak says he'll be pushing for more HST exemptions now that First Nations have secured theirs.
He says the premier wants to give First Nations a break, but asks about seniors who can't pay their hydro bills.
