As you may be aware, Environment and Climate Change Canada’s new Environmental Emergency Regulations, 2019 (the Regulations) came into force on August 24, 2019, replacing the previous version of the Environmental Emergency (E2) Regulations (2011). This email is to inform you that the 2nd version of the Technical Guidelines for these Regulations are available on the Environment and Climate Change Canada website, as of December 30, 2020.

The intent of the Technical Guidelines is to assist regulatees in better understanding the requirements of the Regulations so that they are able to be compliant with the legislation.  The document provides clarification and guidance on questions such as the following:

  • Who do the regulations apply to?
  • Calculating on-site substance quantities and container capacity
  • Benefits of environmental emergency planning
  • Who is required to prepare an environmental emergency plan?
  • How to prepare an environmental emergency plan
  • What to include in your environmental emergency plan
  • Simulating emergency scenarios identified in the environmental emergency plan
  • Notification requirements to the Government of Canada about the charge, management or control of a substance subject to these regulations
  • How chemical substances are evaluated for environmental emergency hazards
  • Failure to comply with the regulations.

Recent Revisions to the Technical Guidelines for the Environmental Emergency Regulations, 2019

In order for this document to correspond to industry’s needs, a second edition of the Technical Guidelines are being published, following the latest publication in December 2019. These amendments provide more clarity and better align with the intentions of the Regulations. A revision history of version 2 is available in the first pages of the document.

IMPORTANT: The Technical Guidelines for the Environmental Emergency Regulations, 2019 are intended to provide contextual information on the Regulations and the Canadian Environmental Protection Act, 1999 (CEPA 1999.). They do not replace CEPA 1999 or the Regulations. Regulatees should refer to CEPA 1999 at and the Regulations at to ensure they are in compliance with the law. Some provisions of CEPA 1999 and the Regulations have been quoted for convenience of reference only and have no official sanction. Should any inconsistencies be found between the Technical Guidelines 2019 and CEPA 1999 or the Regulations, CEPA 1999 and the Regulations will prevail.

Any questions related to the Regulations or the Technical Guidelines should be directed to the E2 Prevention Program officer in your region listed at the following address
