Ethanol in Gasoline

Ethanol is an alcohol that can be produced through fermentation from a number of raw materials, including sugars and grains. In Ontario, corn and wheat are the main materials used to produce ethanol.

Ethanol is often blended with gasoline. A vehicle that is fuelled by an ethanol-blended gasoline will emit smaller amounts of greenhouse gases than it would if fuelled by non-blended gasoline. Ethanol increases the combustion efficiency of fuels, so the vehicle would also emit lower amounts of carbon monoxide, particulate matter and other toxic substances.

Regulation 535/05

Ontario Regulation 535/05: Ethanol in Gasoline (made under the Environmental Protection Act) requires fuel suppliers to ensure an annual average of five per cent ethanol in their gasoline.

This regulation came into effect in 2007 and is a component of Ontario's work to improve the province's air quality and combat climate change. It also helps to reduce our dependency on non-renewable fossil fuels.

Reporting Requirements

Under Regulation 535/05, fuel suppliers are required to submit compliance reports to the ministry by March 31st of the year that follows the compliance year.
