New Substances Notification forms

The New Substances Notification (NSN) forms serve as an aid for complying with the New Substances Notification Regulations (Chemicals and Polymers) and the New Substances Notification Regulations (Organisms). The NSN forms or sections of the NSN forms may be reproduced as often as required.

Interpretation of person certification form

Where one corporation has provided information to the New Substances (NS) program under the Regulations concerning a new substance, the NS program will consider a successor corporation to be the same person as the original corporation for the purposes of subsection 81(1) or 106(1) of the Canadian Environmental Protection Act, 1999 and the Regulations.

Confidential Search Request form

Note: Confidential Search Request was previously referred to as a bona fide intent to manufacture or import.

Any person who intends to manufacture, import or use a substance may seek confirmation that the substance is listed on the confidential Domestic Substances List or Non-domestic Substances List from the New Substances program by providing a Confidential Search Request for the substance.

Pre-Notification Consultation form (PNC)

A PNC is an option for notifiers who wish to consult with the NS program during the planning or preparation of their NSN to discuss any questions or concerns regarding information requirements. A PNC request is recommended when assistance is needed in determining the acceptability of waiver requests, test protocols, consolidated notifications, alternative data, or other endpoints, or when clarification is needed regarding substance classification.

Note: If a notifier is requesting the review of a draft biotech NSN, the PNC form does not need to be submitted; however, the notifier should include an NSN form completed to the best of their ability and indicate clearly in their cover letter that they are submitting the draft for review as a PNC request.

This form is used to nominate a substance for addition to the Domestic Substances List
