Disposal at sea permit application guide

On this page

When any substance is loaded onto a ship, aircraft, platform or other structure and released into the sea or estuarine environment, it is likely to be considered disposal at sea. Disposal at sea is prohibited without a permit issued by the Environment and Climate Change Canada Disposal at Sea Program under the Canadian Environmental Protection Act, 1999 (CEPA).

How substances are permitted for disposal at sea

Only substances listed in Schedule 5 of CEPA are eligible for consideration. Proposed disposal projects are evaluated by regional Disposal at Sea Program staff in accordance with the assessment requirements of Schedule 6 of CEPA.

Applying for a permit has 4 phases (detailed guidance on the permit process requirements is available in the waste type specific permit application guides below):

1. Pre-application

Consult with regional Program staff to ensure all pre-application required information is provided and the assessment is completed prior to submitting the application.

2. Submission of application

The prescribed application form (set out by the Disposal at Sea Permit Application Regulations) and supporting documentation must be completed to meet the requirements outlined in CEPA.

For your convenience, downloadable versions of the permit application form that are specific to the various waste types are available below. You may use these application forms when applying for a permit.

Once you have accessed a form, you can fill in the fields, electronically in the case of the PDF, but you must print the form for submission by mail to the nearest Disposal at Sea Program regional office. You may not be able to save any completed forms. If you prefer receiving a Microsoft Word version of an application form, please contact us at ec.immersionenmer-disposalatsea.ec@canada.ca.

3. Permit application assessment

The information provided in the application is assessed by us and other relevant agencies. The application may also be forwarded to other stakeholders as appropriate. The permit assessment involves a numbers of steps.

There is a 90-day regulated service standard to reach a permit decision once we have notified you in writing that your application is complete. In some situations the time limit will not apply. For example, if additional analysis or consultations are required to meet certain statutory obligations.

We must publish a copy of the permit and its conditions to the CEPA Registry. The start date for loading and disposal at sea is always set to account for the registry publication period (up to 14 days following the 90 day review process).

4. Operations

You may begin project operations on the permit’s start date, and in accordance with the conditions stipulated in the permit.


If necessary, permit conditions can be varied during the specified term of the permit. Any changes made to a disposal at sea permit must be published on the CEPA Registry.

After a permit has been issued, periodic inspections will be conducted at both the load site and disposal site to ensure compliance with the permit conditions. We also conduct representative disposal site environmental monitoring each year.

For information on disposal of uncontaminated organic matter of natural origin; ships, aircraft, platforms or other structures; or bulky substances, please contact the nearest Disposal at Sea Program regional office.
