Importing or manufacturing a new chemical or polymer: prepare the federal notification

Check first

An overseas inventory listing is insufficient. Check Canadian lists, thresholds and any specific conditions before starting the activity.

Confirm the right process

Identify the substance precisely and check its Canadian inventory status; distinguish a new substance from a regulated significant new activity.

Prepare the dossier

Determine the applicable schedule from the substance, quantities and use; gather required identity, properties, hazard and exposure evidence.

Submit the application

Use the notification form and current submission channel; explain any confidentiality or data-waiver requests.

Follow up

Respect the assessment period and notified restrictions; retain correspondence and monitor thresholds requiring an additional submission.
