Mandatory Form Information

Pre-Submission Form 

Please ensure that you have ALL items on the OCS Listing Requirements Checklist.

Pre-submission begins when the OCS publishes an Assortment Needs Bulletin, followed by an opportunity for interested Suppliers (both current and prospective) to pre-submit products they wish to list for sale in Ontario. Suppliers submit an application to share critical information about new products they wish to sell into Ontario’s recreational cannabis market prior to proceeding with a formal product submission. The OCS assesses Pre-Submission Applications and provides all Suppliers with feedback.

Note: Cannabis Suppliers may submit a Pre-Submission Form to OCS for consideration while licensing with Health Canada is still pending. However, following the Pre-Submission Application process, Cannabis Suppliers are not eligible to submit to the Product Call unless they hold the appropriate Health Canada licence that authorizes the sale of cannabis products included in the submission to a provincially-authorized distributor, such as the OCS.

Submission Form 

Eligible Suppliers chosen via the Pre-Submission process are invited to submit through the Product Call Submission Portal by the date listed in the OCS Assortment Needs Bulletin. The OCS evaluates submissions against standardized criteria, provides all Suppliers with feedback, and issues (NTP)s to successful applicant.

Who can I reach out to if I have questions about the Product Call process?

All Suppliers will be assigned a Category Manager to serve as a consistent point-of-contact throughout the Product Call process. Suppliers will receive a response to any inquiry from their assigned Category Manager within five (5) business days.

For general inquiries, please reach out to the OCS Merchandising Team at

Disclaimer:  Nothing in these Product Calls shall be construed as creating any commitment by, or on behalf of, the OCS.  All information provided is subject to change at any time by the OCS at its sole and absolute discretion. For clarity, no cannabis products will be purchased by, or sold to, the OCS unless otherwise authorized by law.
