The number of marine oil spills and amount of oil spilled worldwide has decreased due to improved safety measures, even though the volume of oil carried by ships – whether as cargo or fuel – has increased significantly. The risk of a spill in Canadian waters is low, but should it happen spill response plans are in place.

If a spill occurs, who cleans it up and how? What are the resources available to minimize the environmental damage? How is the recovered oil safely disposed? Who pays for the cost of clean-up and damages as a result of an oil spill?

The purpose of this site is to answer these questions, provide the facts about response to oil spills from commercial ships – whether the oil is cargo or fuel – in Canadian waters and encourage informed conversations on the topic.

This site was created by Clear Seas Centre for Responsible Marine Shipping, an independent not-for-profit research centre that supports safe and sustainable marine shipping in Canada.

Oil Spills in Canada

A growing number of oil spills in Canada are the result of wrecked or abandoned recreational vessels leaking small amounts of fuel or lubricating oil. The Government of Canada has taken steps including a new Wrecked, Abandoned or Hazardous Vessels Act and a comprehensive national strategy to reduce this source of oil spill risk. Most oil spills from commercial ships in Canadian waters are also small.


The National Oil Spill Preparedness and Response Regime, a public-private partnership, provides a framework to address ship-source oil spills in Canadian waters south of 60° North. To protect our environment from the risk of spills, Canada has established three pillars of defence:

Continuously improving measures to prevent oil spills from ships include requirements for:

  • Double hulls
  • Escort tugs
  • Inspections
  • Highly trained local marine pilots to guide vessels in transit as well as traffic control systems and navigational aids

Aerial monitoring activities also contribute to preventing ship-source pollution – as ships in Canadian waters are under air surveillance.

Being prepared to respond to a spill enables responders to act quickly and limit environmental damage. From coastal risk assessments to local and regional response plans, contracts with response organizations, equipment caches, on-water exercises and personnel training, Canada is continually improving its spill response preparedness.

Should prevention efforts fail and an oil spill happens, a safe and effective response must be launched quickly. The polluter – the ship owner or operator that caused the pollution – is responsible for taking the lead to clean up the spill. All commercial ships are required to have a contract with one of Canada’s four government-certified and industry-funded response organizations to conduct clean-up efforts on the polluter’s behalf.

Operations generally follow an Incident Command System with involvement or oversight by the Canadian Coast Guard when the polluter is either unable or unwilling to respond.

Canada applies the internationally established “Polluter Pays Principle” for all costs and damages associated with response, remediation and recovery of the area affected by an oil spill. The polluter pays for damages by drawing from its mandatory insurance and from national and international funds paid by industry, if necessary.


Canada’s response system is a partnership between government and industry. It relies on relationships among key partners, First Nations and other stakeholders.

The Polluter

Canada puts the onus for cleaning up a ship-source spill on the polluter. Ships entering or transiting Canadian waters are required to have a Shipboard Oil Pollution Emergency Plan, which tells the ship's crew what actions to take and who to contact when the risk of an oil spill is imminent or when an incident has occurred.

All tankers of 150 gross tonnes (approximately 20-30 metres in length) and all vessels of 400 gross tonnes (approximately 30-40 metres in length) or greater, as well as all oil handling facilities, must have an arrangement with a certified response organization to operate in Canadian waters. If a spill occurs, the polluter must report the spill and take action to respond. If the spill exceeds the ship’s clean-up capacity, the ship can contract its response organization to assist with the clean-up efforts.

Canadian Coast Guard

The Canadian Coast Guard is an operating agency of Fisheries and Oceans Canada. During clean-up operations, the Canadian Coast Guard takes the lead in the response effort and works with the polluter and other stakeholders to ensure an appropriate response.

The Canadian Coast Guard takes the lead in the response effort and works with the polluter and other stakeholders to ensure an appropriate response.

The Canadian Coast Guard does not take the lead in responding to marine pollution incidents outside its mandate, such as pipeline spills and land-based spills. However, the Coast Guard can provide assistance to those responsible for responding to such incidents.

Response Organizations

Canada’s four response organizations have area-specific response plans ready to deploy at short notice for all of Canada’s waterways south of 60° North and extending up to 200 nautical miles offshore. Transport Canada conducts ongoing capacity and procedure audits and re-certifies each response organization every three years, according to specific technical and operational requirements.

Governments’ Response to Oil Spills

Other federal government agencies also have a role in spill response in Canada.

Fisheries and Oceans Canada defines the scope and framework within which the Canadian Coast Guard will operate, through the national Marine Spills Contingency Plan.

Environment and Climate Change Canada is responsible for providing environmental and scientific advice during an oil spill response, such as weather conditions, spill movement, sensitive habitats and species at risk.

Transport Canada manages and oversees the National Oil Spill Preparedness and Response Regime. It assesses marine incidents risks, monitors the waterways, ensures Canada has the appropriate capacity to respond to oil spills, and that response organizations operate according to regulations in place.


Indigenous peoples have been governing marine territories using their own legal traditions since time immemorial and continue to fulfil their responsibility to steward and protect their ecosystems.

Coastal First Nations, Inuit and Métis have an inherent right to govern their territories, recognized under s. 35 of the Constitution Act, 1982. This right includes the jurisdiction to regulate the use of its lands and waters. Reconciliation of Canadian and Indigenous sovereignties call for Canada’s respectful attention to First Nations, Inuit and Métis’ need to safeguard their waters.

Provincial and Territorial

Provincial and territorial governments, through their respective Ministries of Environment and Emergency Management agencies, liaise with all oil spill response partners during clean-up and recovery operations to oversee the land between high- and low-tide marks.


Local government resources may be able to support response operations by providing local knowledge, personnel or equipment.

Canada-United States Collaboration
and Arctic Nations Cooperation

A formal Canada-US Joint Marine Pollution Contingency Plan is in place to respond to cross-border spills, indicating how the Canadian and US Coast Guards will collaborate to coordinate the response.

Canada works with the seven other Arctic nations to coordinate response to any oil spill occurring north of 60° North in accordance with the Arctic Council Agreement on Cooperation on Marine Oil Pollution Preparedness and Response in the Arctic.

Indigenous, Coastal Communities
and the Public

Indigenous and coastal communities may be the first to identify an oil spill on the coast, particularly in remote areas. Indigenous communities also possess Traditional Knowledge of the marine and land resources including sensitive coastal areas and species at risk. As knowledge holders, Indigenous communities may be able to contribute valuable insights to the response effort.

The public can also provide key local knowledge to the response effort, such as reporting affected wildlife to the authorities. Although members of the public are not involved in the response, they may volunteer through official channels.

An oil spill response progresses through three stages:

  1. Evaluate the spill
  2. Clean up the spill (on water and on shore)
  3. Dispose of the oily waste

Within each stage, responders evaluate many factors to decide how best to contain and clean up the spill. The safety of responders and the public is always the priority in all phases of the operation.

1. Evaluation

Evaluating an oil spill needs information gathered about the area before the spill occurs as well as information about the spill itself. Access to accurate information helps responders make better decisions and act faster when a spill occurs.

Advance Information for Spill Response
The on-water and shoreline oil spill clean-up methods in Canada are based on data collected by Environment and Climate Change Canada’s National Environmental Emergencies Centre and Regional Environmental Emergency Teams. Data gathering includes identifying and mapping sensitive areas, habitats and wildlife populations to be able to provide response teams with expert scientific advice during a spill response.

Response organizations also collect coastal sensitivity data working with local communities including First Nations to develop area-specific response strategies.

Shoreline Mapping

To identify environmentally sensitive and culturally significant areas along Canada’s coasts, Environment and Climate Change Canada gathers detailed coastal information through shoreline mapping. Helicopters flying at 300 metres collect photos and videos of the shore, especially areas between the high- and low-tide marks.

Shoreline mapping provides key information about the type of shorelines – such as sand, mud, rocks, cliffs, and tidal flats – and wildlife in the area. The location-specific imagery is made available to response teams for effective decision-making and rapid deployment when an oil spill occurs.

  • Sand
  • Mud
  • Rocks
  • Cliffs
  • Tidal flats
  • Wildlife

Situational Information for Spill Response
When deciding how to respond, responders must consider variables such as:

  • Type of oil
  • Amount of oil
  • Location of the spill
    • Distance from response resources and time to reach the spill
    • Distance from the shoreline
    • Type of water (fresh, salt, or mixed)
    • Type of shoreline (rocky, sandy, marshy)
    • Proximity to sensitive marine habitats or other important areas
  • Wind and wave action
  • Currents and tides
  • Temperature of the air and water
  • Presence of ice, rain or snow

2. Clean Up

A spill clean-up effort typically consists of containing the spill, cleaning up the oil from the water, and cleaning up the shores, if affected by the spill.

First Stage: Contain the Spill

Containing the oil is critical to limit damage and to clean up as much oil as possible. Containment booms (floating barricades) are the first line of defence to prevent the slick from spreading and reaching sensitive habitats and shorelines.

Second Stage: Clean oil from the water

Once the oil is contained, responders assess different response measures to mitigate damage. When considering any clean-up method, responders use a Net Environmental Benefit Analysis approach to identify the approach that will minimize harm to people and the environment.


  • Mechanical

  • Natural


  • Chemical oil

  • In-situ

Mechanical recovery

Mechanical recovery is the most often used response method in Canada. During mechanical recovery, containment booms are deployed around the spilled oil. Response vessels then use sorbent pads, skimmers and vacuum systems to sop, scoop or pump the oil out of the water. The retrieved oil is collected in the response vessel then transferred to storage barges and taken to a disposal centre. Mechanical recovery can be limited by:

  • Rough weather conditions with strong currents and waves

  • Capacity of skimming vessels and storage barges

  • Thickness of the oil on the water and how quickly it spreads, evaporates, or dissolves

Natural recovery

Letting the oil disperse naturally is an approach most often used in harsh weather or when spills occur far from shore. Where natural recovery is the best strategy, response teams still monitor the spill closely in case additional response measures need be deployed later. Strong winds and high waves can create unsafe conditions for responders and make mechanical recovery difficult or impossible. In severe conditions, oil weathers and breaks down more quickly, encouraging dispersion. The dispersed oil particles are eventually broken down by ocean bacteria that have evolved to eat hydrocarbons.

Chemical oil dispersants

Used internationally and currently under study in Canada , chemical oil dispersants can be applied to a spill to quickly break down the oil into smaller droplets – like dish soap on grease. The small particles are then degraded through natural processes such as oil-eating bacteria . Dispersants can be effective to treat large oil slicks, to limit the impact of oil on sensitive habitats, wildlife or shorelines, and to respond to a spill under rough wind an sea conditions. They are usually sprayed using aircraft or vessels equipped with spraying arms. Learn more about oil dispersants here.

In-situ burning

In-situ burning is a response measure where the oil slick is ignited to burn the oil off the water’s surface. Prior to ignition, the slick is contained using fire-resistant booms. In calm conditions and if located far away from shorelines and populated areas, in-situ burning can rapidly reduce a thick slick of oil. As this method can create toxic fumes and residues that can harm the marine environment and people, in-situ burning is assessed on a case-by-case basis in Canada.

Third Stage: Clean Oil from the Shore

If oil reaches the shore, response teams are mobilized for shoreline clean-up. Oil can be manually recovered from the shore or washed off the beaches into the water to be collected off the water’s surface. The most appropriate methods to use depend on the type of shoreline as well as proximity to people, sensitive ecological areas, wildlife and key natural resources. Shoreline clean-up methods include:

  • Sorbents
    Natural or synthetic materials used to absorb oil

  • Shoreline flushing
    Using water to refloat oil for easier recovery

  • Berms
    Ledge made of soil, sand or other materials, built to contain oil and stop it from spreading further

  • Vacuums
    Devices that remove the oil from the ground by suction

3. Disposal of Oily Waste

Oily waste can be highly toxic and must be handled, treated and disposed of safely. In Canada, the disposal of oily waste is the responsibility of the polluter.

Different types of oily waste are usually stored separately as the disposal method depends on the type and level of contamination of the recovered oil.

If oil is recovered quickly and is not contaminated by water and debris, it can be sent to recycling facilities to be reprocessed. Heavily contaminated oil is usually taken to a disposal site.

Disposal methods depend on the :

  • Type of oily waste

  • Amount of oil recovered

  • Location of the spill

  • Capacity required to store and transport the recovered oil

  • Availability of storage, treatment and disposal facilities

  • Costs involved

How do different types of oils behave in water?

Not all types of oil behave the same way in water; the length of time oil will remain on the surface of the water before spreading, evaporating, dissipating or sinking can vary.

Overall, oils can be categorized into two groups:

  • Heavy fuel oil
  • Marine diesel oil
  • Low sulphur marine diesel oil
  • Crude oils (medium, light)
  • Heavy oils (conventional, diluted bitumen, bitumen mixed with non-persistent oil)
  • Bitumen (extra heavy oil)
Characteristics (compared to non-persistent oils)
  • Thicker consistency (higher viscosity)
  • Slower to dissipate with more residue left behind
  • Density of residue can be high enough that portions submerge or sink
  • Interaction with sediment can make portion submerge or sink
  • Residue can have prolonged impact on marine wildlife and environment
  • Requires active response operations
Common behaviour in water
  • Spreads
  • Emulsifies
  • Interacts with sediment on shoreline and seafloor
  • Gasoline
  • Kerosene
  • Diesel
  • Liquefied natural gas
  • Jet fuels
Characteristics (compared to persistent oils)
  • Thinner consistency (low viscosity)
  • Quicker to dissipate with less residue left behind
  • Higher toxicity for water and air hazard (more volatile)
  • Environmental impacts tends to be localized but acute
  • Interactions with sediment can make portion submerge or sink
  • Rarely requires active response operations
Common behaviour in water
  • Spreads
  • Evaporates
  • Disperses
  • Dissolves


To assist heavier crude oil or bitumen from Alberta to flow through pipelines it is mixed or diluted with lighter petroleum products. The resulting diluted bitumen is an oil blend that is lighter than water and, like most crude oils, floats if spilled in the ocean.

Diluted bitumen reacts similarly to conventional crude oils when spilled in
water. Despite concerns that it sinks faster than other types of oil making it difficult to recover in the event of a spill, research, including lab, pilot tests and field trials, as well as spill response experience, has shown that diluted bitumen will float for at least two to three weeks depending on water conditions such as temperature, wave action and currents.

Experiments and real-life spill experience by the Western Canada Marine Response Corporation also show that diluted bitumen can be recovered from the water surface using conventional skimmers, booms and pads.


Funding Oil Spill Response
In Canada, oil spill response organizations are funded by industry. For preparedness, oil handling facilities and commercial ships operating in Canadian waters pay annual fees to the relevant response organization to cover that response organization’s operating costs.

The Polluter Pays Principle
Under the Marine Liability Act , if a ship spills oil of any kind in Canada’s waterways, the polluter is liable to pay for clean-up costs. The shipowner is the primary source of compensation, covering eligible costs up to a limit. If claims submitted to the shipowner exceeds their limit of liability, additional compensation may be sought from other sources funded by industry.

One of those sources is Canada’s Ship-source Oil Pollution Fund. Created from industry levies, the Fund has unlimited capacity to reimburse all eligible claims for loss or damage caused by ship-source oil spills in Canadian waters.
