Regulatory spill reporting for owners of pollutants
Owners of pollutants are required by provincial law to report spills if:
- you allowed the spill to occur
- you had control of the substance immediately before the spill occurred
- you are a member of a public agency (such as Metrolinx) and, to your knowledge, the spill has not already been reported
Owners of pollutants reporting spills are required to contact the Spills Action Centre by telephone:
The telephone lines above are available 24/7.
In addition to contacting Ontario’s Spills Action Centre, the spill must also be immediately reported to:
- the local municipality
- the owner of the substance (if known)
- the person in control of the substance (if known)
When reporting the spill, the owner of the pollutant will be asked to provide:
- their name and phone number
- name and phone number of the person or company in control of the product spilled
- date, time and location of the spill
- duration of the spill (if known) and whether the spill is ongoing
- type and quantity of pollutant spilled, including hazard level or toxicity information
- source of the spill and information on the cause
- description of adverse effects
- environmental conditions that affect the spill (weather, traffic, etc.)
- actions being taken to respond
- other agencies and parties responding
After the owner of the pollutant reports the spill, an environmental officer will:
- document the information and actions taken
- assess the environmental and health impacts based on gathered information
- ensure responsible parties respond to spill events as per their legislative responsibility
- track and follow up on required cleanup activities
- provide advice and information related to spills or environmental incidents
- coordinate a response with other agencies, if needed
- initiate government response when required
More details on regulatory reporting can be found in Ontario Regulation 675/98.
Cleanup and remediation
Under the Environmental Protection Act, it is the duty of the owner or controller of a spilled pollutant to clean up a spill. They must do everything practicable to prevent and eliminate the negative effects from a spill, including restore the natural environment to its original state.
If those responsible for a spill cannot or will not respond to properly clean up the spill, the Minister of the Environment, Conservation and Parks has the authority under the Environmental Protection Act to order those responsible to do so.
Spill clean-up can require specialized response (HAZMAT) and equipment. Licensed spill contractors can be hired to clean up a spill. There are also rules for the disposal of pollutants and spill contractors are familiar with these rules. If you are not sure how to handle a spill or the disposal of pollutants contact the Spills Action Centre at
Spill cost recovery
High risk spills can require significant involvement and resources by the province to actively oversee and monitor the clean-up.
The Ontario government can recover reasonable costs and expenses that provincial agencies incur to respond to a spill, including any steps taken to ensure those responsible for the spill:
- prevent or minimize the impacts of contaminants on human health and the environment
- ensure the appropriate steps are taken to restore the natural environment
- prevent or reduce the risk of future spills into the natural environment
This can include time that provincial staff spend at the site of the spill, sampling and monitoring costs and any other related costs or expenses that provincial agencies incur to ensure negative effects from the spill are adequately reversed.
