Interested contractors and suppliers may request to be placed on the OCSL at any time. However, DCC is requesting that interested contractors and suppliers submit a request to be placed the OCSL as soon as possible, preferably by March 4, 2026. DCC will require ten (10) business days to process an application for the OCSL.
Contractors and suppliers that want to be added to the OCSL, must submit a request through this MERX posting and therein indicate their preferred official language (English or French).
IMPORTANT: Contractors and suppliers that were placed on the previous OCSL (April 1, 2023, to March 31, 2026) must re-apply to be placed on the OCSL for April 1, 2026, to March 31, 2029.
The language selected by the applicant for this OCSL will be the only language used for the tender documents, the contract documents and communication for all future tenders and during the execution of any resulting contract. The language selected will apply for the duration of the OCSL.
Faxed, mailed, or emailed submissions will not be accepted.
The OCSL will be used to tender construction services (commercial, residential, industrial, institutional, civil) with an estimated value of $10 million and below. As "Opportunities to bid" arise, DCC will invite all contractors and suppliers on the OCSL to bid on the work.
Contractors and suppliers will be invited electronically through MERX and may, at the discretion of DCC, be required to attend a site meeting prior to a tender closing. Tenders will close electronically through MERX.
Contractors and suppliers who apply to be placed on the OCSL will require an active MERX account to submit electronic bids.

Please contact MERX for information on how to open or reactivate an account.
To bid on a tender call, a bidder must be registered on the OCSL used for the tender call. If the bidder's legal name does not appear on the OCSL, DCC may consider their bid to be non-compliant. If you change your business name, it is therefore very important that you notify DCC and consider making the change to your MERX account.
DCC reserves the right, at its sole discretion, to:
Continue using existing source lists that may already be in place for similar or related services such as existing Quick Response Tender (QRT) source lists,
Establish other source lists for specific categories of construction services which may require different pre-qualification requirements, such as Quick Response Tender (QRT) source lists. Such other source lists will not be advertised through this OCSL. Such other source lists will be advertised openly on MERX on a case-by-case basis,
Verify which contractors have submitted bids under the OCSL, verify if those that did not submit bids are still interested to be on the OCSL and remove from the OCSL those contractors that are no longer interested,
Require additional pre-qualification requirements for any specific tenders done through the OCSL,
Elect to post any tender openly on MERX in lieu of this OCSL if DCC deems that an open tender would provide the potential for more competition,
Tenders may be set aside for Indigenous businesses in accordance with the Procurement Strategy for Indigenous Business (PSIB). In such cases, all contractors and suppliers on the Open Construction Source List (OCSL) will receive an invitation to bid; however, the MERX advertisement will clearly state that the opportunity is reserved for Indigenous businesses under PSIB. To qualify, the Indigenous business must be registered in Indigenous Services Canada’s (ISC) Indigenous Business Directory (IBD). If you are forming a Joint Venture (JV) to bid on a contract set aside for Indigenous businesses, at least
