Finally, some good news for Ontario drivers. If you've been waiting to fill up your tank, this weekend is the time to do it. Based on insights from industry experts, Ontario gas prices are expected to drop three cents at midnight tonight. At most GTA gas stations, this would bring the average price of gas down from 124.9 cents per litre to 121.9 cents per litre by tomorrow, reports GasBuddy Analyst Dan McTeague.\nOntarians have been seeing a gradual rise in the price at the pump over the last several weeks, especially since April 1st, when the federal government's new carbon tax of 4.42 cents per litre, plus HST, came into effect on gasoline.\nA Friday win for drivers!!

That's because gas prices have actually been dropping to offset the cost to consumers of the federal carbon tax. According to Dan McTeague, "A trade war between the United States and China the number one and two global economies — many believe that they could have an effect on driving prices down as it would drive demand to a much lower level."\nAccording to the provincial government's motor fuel prices webpage, the federal carbon tax is scheduled to increase on an annual basis. By 2022, the tax is expected to reach 11.05 cents per litre.\nThe provincial government also noted on its webpage that although the federal carbon tax is not part of the wholesale price of gasoline, it is treated like any other tax, which is reflected in the retail price of petroleum.\nIn Case You Missed It ...
