Defence Construction Canada - National Capital Region - Ottawa, Ontario

**Tender summary:** Defence Construction Canada (DCC) is accepting applications from contractors and suppliers who want to join an Open Construction Source List (OCSL) for future construction opportunities in Northern Canada. The work may include commercial, residential, industrial, institutional, and civil projects in locations such as Yellowknife, Inuvik, and North Warning System sites in the Northwest Territories and Yukon. Nunavut and Goose Bay, Newfoundland and Labrador are excluded. The source list will cover projects valued at approximately $10 million or less during the period from April 1, 2026, to March 31, 2029. Contractors on the list may later be invited through MERX to bid on individual opportunities. DCC may require site meetings, additional pre-qualification, performance standards, or Indigenous-business participation requirements for specific tenders. **Key requirements and deadlines:** - Applications must be submitted electronically through the MERX posting; faxed, mailed, and emailed submissions will not be accepted. - An active MERX account is required. - Applicants must select either English or French as their official language for future tender and contract communications; this choice applies for the duration of the source list. - DCC recommends applying as soon as possible, preferably by March 4, 2026. It expects to take approximately 10 business days to process an application. - The listed closing date is March 31, 2029, at 2:00 p.m.; applicants should confirm how this date applies to source-list requests in the official notice. - Businesses already on the previous 2023–2026 source list must re-apply. - The legal business name must appear on the OCSL for a business to bid on future tender calls; changes to the business name should be reported to DCC and reflected in MERX. This opportunity appears potentially relevant to Canadian construction contractors and suppliers that can serve Northern Canada and are prepared to monitor and bid on future DCC tenders. Being added to the OCSL would not guarantee invitations, contracts, or work. Some opportunities may be reserved for Indigenous businesses or include Indigenous subcontracting requirements. Review the complete official MERX notice and any linked documents for the application procedure, eligibility or pre-qualification details, performance requirements, and applicable amendments before submitting an application: https://www.merx.com/public/solicitations/3804640551/abstract?language=EN

Defence Construction Canada - Ontario Region - Kingston, Ontario

Defence Construction Canada (DCC) is creating an Open Construction Source List for construction work supporting CFB Petawawa and its satellite site in Pembroke, Ontario. The list is intended for commercial, residential, industrial, institutional, and civil projects valued at up to approximately $10 million. This is not a contract for one specific project. Contractors and suppliers placed on the list may be invited through MERX to bid on future opportunities during the three-year period from April 1, 2026, to March 31, 2029. Site meetings may be required, and future tenders may include additional qualifications or requirements. Businesses may request placement on the list at any time through the MERX posting, but DCC asks applicants to apply as soon as possible, preferably by March 4, 2026. DCC indicates that processing an application may take 10 business days. Applicants must select either English or French; that language will be used for future tender and contract documents and communications for the duration of the list. Applications must be submitted electronically through MERX. Faxed, mailed, or emailed submissions will not be accepted, and an active MERX account is required. Businesses already listed under the previous 2023–2026 source list must re-apply. The company’s legal name must appear correctly on the list when bidding, or DCC may consider a bid non-compliant. Some future opportunities may be reserved for Indigenous businesses under the Procurement Strategy for Indigenous Business, or may require subcontracting with businesses registered in Indigenous Services Canada’s Indigenous Business Directory. DCC may also use other source lists, advertise certain tenders openly, verify ongoing interest, or remove businesses based on performance or other conditions. This opportunity appears potentially relevant to construction contractors and suppliers serving the Petawawa/Pembroke area, but the available description does not establish that any particular business qualifies. Review the complete official MERX notice, application instructions, forms, and any applicable requirements before submitting an application or bid: https://www.merx.com/public/solicitations/3776296414/abstract?language=EN. Note that the supplied location field says Kingston, while the tender description identifies CFB Petawawa and Pembroke; this should be confirmed in the official notice.

Defence Construction Canada - Ontario Region - Kingston, Ontario

Defence Construction Canada (DCC) is creating an Open Construction Source List (OCSL) for construction work supporting 8 Wing Trenton and satellite sites in Belleville, Peterborough, and Prince Edward County, Ontario. The work may include commercial, residential, industrial, institutional, and civil construction, with individual opportunities generally estimated at $10 million or less. Businesses that are accepted onto the list may be invited through MERX to bid on future projects during the period from April 1, 2026, to March 31, 2029. Being on the list does not guarantee that a business will receive work or win a contract. DCC may impose additional requirements for specific tenders, use other source lists, or advertise opportunities openly instead. Applications must be submitted through the MERX posting only; faxed, mailed, or emailed submissions will not be accepted. Applicants must indicate either English or French as their preferred official language. That language would apply to future tender and contract documents and communications for the duration of the source list. An active MERX account is required. Businesses already listed on the previous 2023–2026 OCSL must re-apply. DCC requested applications as soon as possible, preferably by March 4, 2026, and indicates that processing may take 10 business days. The posting is shown as open until March 31, 2029, at 2:00 p.m.; however, the application timing and any current intake instructions should be confirmed in the official notice. Future bids may involve electronic submission through MERX, site meetings, additional pre-qualification, performance requirements, or Indigenous procurement requirements. This opportunity appears potentially relevant to Canadian contractors or suppliers with suitable construction capabilities and an interest in federal defence-related work in the listed Ontario locations. The tender data identifies Kingston as the location, while the description focuses on 8 Wing Trenton and nearby satellite sites, so the precise geographic scope should be verified. Review the complete MERX notice, application requirements, forms, eligibility conditions, and any updates before applying or submitting a bid: https://www.merx.com/public/solicitations/3776296415/abstract?language=EN

Defence Construction Canada - Ontario Region - Kingston, Ontario

Defence Construction Canada (DCC) is accepting applications from contractors and suppliers to join an Open Construction Source List (OCSL) for construction work for the Department of National Defence. The work appears to cover commercial, residential, industrial, institutional, and civil projects at CFB Borden and satellite sites in Meaford, Owen Sound, and Barrie, Ontario. The tender record lists Kingston, Ontario as the location, so this should be confirmed in the official notice. The source list will support future tenders valued at approximately $10 million or less during the three-year period from April 1, 2026, to March 31, 2029. Being placed on the list would allow a contractor or supplier to potentially receive invitations to bid on future opportunities; it is not an award of work or a guarantee of contracts. Applications must be submitted electronically through the MERX posting. Faxed, mailed, and emailed applications will not be accepted. Applicants need an active MERX account and must select either English or French as their preferred official language. That language will apply to future tender and contract documents and communications for the duration of the source list. Applications may be submitted at any time before the source-list closing date of March 31, 2029, at 2:00 p.m. Eastern time, but DCC requested applications as soon as possible, preferably by March 4, 2026. DCC states that processing an application may take 10 business days. Contractors and suppliers listed on the previous 2023–2026 source list must re-apply for this new period.

Specific future tenders may include additional pre-qualification requirements, site meetings, Indigenous business set-asides or subcontracting requirements, and other conditions. DCC may also use other source lists or issue some opportunities openly on MERX instead.
