TORONTO - Ontarians should brace for immediate price hikes on electricity, gasoline, diesel, home heating oil and natural gas starting Canada Day.

The province's move to a harmonized sales tax will mean increases for about 17 per cent of purchases previously exempt from the provincial sales tax.

The change combines the five per cent Goods and Services Tax with the eight per cent Retail Sales Tax into a 13 per cent HST.

In addition to energy, many services will also face higher taxes including funerals, Internet fees, hair cuts and dry cleaning.

Premier Dalton McGuinty says he's confident businesses will pass along HST savings in the form of lower prices, and also be able to create 600,000 jobs over the next decade.

But the opposition parties call the HST a "greedy tax grab," and warn it will hurt consumers when they can least afford it.

The HST will not apply to resale homes, but will apply to new homes costing over 400-thousand dollars, although there are rebates of up to 24-thousand dollars.

Going to the movies or a sporting event could actually drop in price because they had been subject to a 10 per cent PST plus the GST.

Ontario has exempted newspapers and prepared meals and drinks costing under four dollars from the HST.

And Ontario First Nations will get the same point-of-sale exemption for the HST that they've had for decades with the provincial sales tax, but it won't kick in until September 1.
