Register for Industrial Emissions Reporting

Operators that are required, under the GHG Emission Reporting Regulation, to report greenhouse gas emissions must register their facilities through the Single Window Reporting System.

To determine whether a facility has an obligation to register, it must forecast no later than February 28 of the reporting period. 

Operators that forecast the potential to exceed the 10,000 tonne threshold must complete a registration form and submit it to the Director, in the form prescribed, by March 31 of the reporting period. If an operation is initially forecasted to emit less than 10,000 tonnes of carbon dioxide equivalent during the reporting period, but after February 28, it is determined that the operation’s emissions are equal to or greater than 10,000 tonnes (not including carbon dioxide produced from biomass listed in Schedule C), a completed registration form must be submitted within 90 days of the date of that determination.

A company is required to submit separate registration forms for each single facility operation, linear facilities operation or electricity import operation.

The registration process consists of:

  • entering the necessary administrative information and comments into the Information Manager module of the Single Window GHG Reporting System at Environment Canada's Single Window; and
  • sending an e-mail to, stating that registration for the reporting operation has been completed.

This process must be completed by March 31, for the previous year's emissions. For questions regarding the registration process, contact
