The disposing of waste oil in Canada is regulated by the Canadian Environmental Protection Act. Waste oil is considered hazardous waste and must be disposed of in a safe and environmentally responsible manner. Disposing of used oil in landfills is prohibited.
Waste oils including antifreeze, grease, cooking oils and motor oil should be stored in suitable tanks or containers until disposal. Waste oil storage tanks must comply with federal regulations. Waste oils should never be stored for more than one year.
Many Canadian provinces and territories provide recycling programs for motor oil and filters, which can damage sewer pipes and pollute ground water if allowed to drain. The used oil can be disposed of at many gas stations or hazardous waste depots.
Cooking oils and kitchen grease can damage municipal pipes if poured down the drain. Some Canadian municipalities provide compost bins to dispose of household fats and oils. Used cooking oils can also be sealed in a container and placed in the garbage for regular pickup.
The purpose of the Canadian Environmental Protection Act is to prevent contamination of the environment and to minimize the impact of hazardous waste on human health. Provincial regulations may override federal regulations if a province's environmental guidelines for storing waste oil are more restrictive.
