5. Denatured fuel ethanol is commercially manufactured ethanol containing a denaturant, as required by the Denatured and Specially Denatured Alcohol Regulations-SOR/2005-22, which makes ethanol unsuitable for beverage or medicinal use. Denatured fuel ethanol is intended to oxygenate gasolines containing that component and is used only as a component of automotive spark ignition fuels.
It must comply with Canadian General Standards Board standard CAN/CGSB-3.516-2011 - Denatured Fuel Ethanol for Use in Automotive Spark Ignition Fuels.
