Standards and codes of practice

Comply with the fish and fish habitat protection provisions of the Fisheries Act by incorporating measures to avoid:

If you can't avoid risks to fish and fish habitat by implementing the measures to protect fish and fish habitat, check to see if there are standards or codes of practice that apply to your project.

A code of practice specifies conditions and measures for managing risks to fish and fish habitat.

A standard outlines how a specific management measure should be designed and implemented to achieve its objective.

Standards and codes of practice can relate to works, undertakings and activities during various phases of their life cycle, such as construction, operation, maintenance or decommissioning.

You may need to request a project review if the codes of practice don't apply to your project.

How to use the codes of practice

Section 1 describes the works, undertakings and activities addressed by the code of practice and the risks to fish and fish habitat which can be mitigated by following the code of practice. You will also find a link to contact information in case you have further questions.

Section 2 helps you determine if you can apply the code of practice to your project and requests that you notify us when you use the code of practice.

Section 3 outlines measures to follow. Review the complete set of measures and only apply the measures that are applicable to your project.

Section 4 provides a glossary to ensure that key terms are understood.

How to use a standard

Standards are not considered stand-alone documents.

They can be referenced in an instrument (for example, codes of practice, regulations or authorizations), or they may also be referenced by the proponent in a project plan, request for review or application for authorization. Provinces, territories and industry partners may also choose to reference standards in their guidelines or regulations as appropriate.

Interim standard: in-water site isolation

View the interim standard for in-water site isolation.

This interim standard provides national guidance for isolating a work site when it is located in a watercourse or water body. In-water site isolation may be required to support the construction of new infrastructure or to support maintenance or removal activities associated with existing infrastructure. This standard includes guidance related to the following 5 methods:

In-water site isolation is a mitigation measure that is implemented during in-water work to manage sediment laden water. The objective of the measure is to reduce the intensity, spatial scale and duration of sedimentation of fish habitat resulting from the project. This standard provides guidance to proponents on how to implement in-water site isolation. It is intended for use in the installation, maintenance, monitoring and removal of in-water isolation methods occurring within:

The type of watercourse or water body and site-specific conditions will often inform the preferred method(s) of in-water site isolation.
