Businesses should confirm whether they can provide all required items—or whether partial bids are permitted—before investing time in a response.

Defence Construction Canada - Ontario Region - Kingston, Ontario

This appears to be an Advance Procurement Notice—not a bid call or request for proposals—for approximately $22 million in renovation work at accommodation Buildings A-147 and A-149 at CFB Borden, Ontario. The work is expected to include life-safety improvements, building-envelope upgrades, electrical and mechanical upgrades, and roof replacements. The anticipated solicitation is expected to be posted in November 2026, subject to Department of National Defence approval. The notice shows a closing date of October 27, 2026 at 2:00 p.m.; confirm what this date applies to in the official notice, since the APN is preliminary and the future solicitation may have separate deadlines. A Designated Organization Screening (DOS) security clearance is anticipated. Businesses that do not already hold the required clearance may be able to begin the sponsorship process through Defence Construction Canada’s Industrial Security Program. Sponsorship is discretionary, does not guarantee clearance, and must be started before the anticipated solicitation is advertised. The APN number to reference is 86114. The project may include an Indigenous-business participation component under the Procurement Strategy for Indigenous Business. The notice does not guarantee that the project will proceed, that a solicitation will be issued, or that security clearances will be granted in time. The tender data lists Kingston as the location, while the project description identifies CFB Borden; this apparent inconsistency should be checked. Businesses considering this opportunity should review the official MERX notice, confirm the applicable deadlines and requirements, and contact DCC directly before taking action.Official source: https://www.merx.com/public/solicitations/4093079871/abstract?language=EN

Defence Construction Canada - Ontario Region - Kingston, Ontario

This appears to be an Advance Procurement Notice from Defence Construction Canada for a potential warehouse construction project at CFB Trenton, Ontario. The project would involve general contracting, materials, labour, and construction of an approximately 1,554 m² facility for the CADSS/MAJAID unit, including warehouse space, parachute-related work areas, a carpentry shop, storage, offices, and areas for forklifts and other machinery. The estimated contract value is approximately $11 million to $13 million. The anticipatedprocurement is expected to use two stages: Step 1, a Request for Expression of Interest, followed by Step 2, a tender phase. Both stages are anticipated for fall 2026, subject to approval by the Department of National Defence. The notice currently shows a closing date of October 27, 2026 at 2:00 p.m.; confirm how this date applies because this notice is not itself a bid solicitation. Security requirements are expected. The anticipated level is Designated Organization Screening (DOS). Contractors that do not already hold the required clearance may wish to review DCC’s Industrial Security Program sponsorship process and reference APN number TRS18081_73944. Sponsorship and clearance are not guaranteed, and the tender documents may impose additional timing and eligibility requirements. The project may also include participation requirements for Indigenous businesses under the Procurement Strategy for Indigenous Business. A contractor potentially matching this opportunity should review its capacity for a large design-bid-build warehouse project, security obligations, bonding and insurance requirements, and ability to work in the Trenton area. The notice states that contractors must submit the required Step 1 response, security sponsorship materials where applicable, and a Step 2 tender to proceed through the clearance process. This is not a bid call and does not guarantee that the project will proceed. The project location is described as Trenton, although the listing metadata identifies Kingston, so this should be confirmed. Review the complete official notice and all later solicitation documents on the official MERX/DCC sources before taking action or submitting any response.
