Department of Public Works and Government Services (PSPC) - *Canada, Gatineau, Quebec

This open tender is for multidisciplinary environmental consulting services for Public Works and Government Services Canada (PSPC) and other federal departments. PSPC appears to be seeking consulting firms to establish Standing Offers, meaning work would be assigned only when specific projects arise rather than guaranteed immediately. Potentially relevant services include environmental impact assessments, permitting and related studies; environmental management for federal facilities; contaminated-sites consulting; remediation planning; site supervision; and cost estimating. Projects may involve federally controlled sites, including contaminated locations in remote Northwest Territories communities. The Standing Offer period is described as 3 years, with up to 3 additional optional years. The tender lists Canada and Gatineau, Quebec, while the work may occur at sites in the Northwest Territories and elsewhere. The closing time is November 30, 2026, at 2:00 p.m. The notice indicates that firms should have relevant environmental engineering and consulting expertise, but this summary does not determine whether any particular business qualifies. No tender documents were provided with the listing. Review the official notice and all procurement documents for mandatory experience, personnel, licensing, insurance, Indigenous or northern-community requirements, security or registration conditions, submission instructions, and the precise closing time and time zone before deciding whether to submit a bid.Official source: https://portal.us.bn.cloud.ariba.com/dashboard/public/appext/comsapsbncdiscoveryui#/Rfx Event/preview/1110027991?an Id=ANONYMOUS

Defence Construction Canada - National Capital Region - Ottawa, Ontario

This appears to be an Advance Procurement Notice from Defence Construction Canada for large-scale facilities maintenance and support services in Northern Canada. It is not currently a bid solicitation or request for proposals, and there is no guarantee that the planned contracts will proceed. The anticipated work could cover approximately 100 buildings and related infrastructure, with an estimated total area of 60,000 m². Services may include building and equipment maintenance, HVAC, electrical, plumbing, fire and life-safety systems, generators, security systems, janitorial services, landscaping, pest control, hazardous-waste and environmental services, snow and ice control, waste management, utility support, help-desk services, emergency response, and maintenance-program management. Potential locations include Churchill, Manitoba; Inuvik and Yellowknife; Whitehorse; and several Nunavut locations, including Iqaluit, Resolute Bay, Eureka, Rankin Inlet, Gascoyne Inlet, and Nanisivik Naval Facility. Thenotice anticipates two possible contracts: one for Manitoba, the Northwest Territories, and Yukon, with a potential estimated value of $240 million; and one for Nunavut, with a potential estimated value of $225 million. Each could have an initial five-year term plus two three-year options, for a possible total of up to 11 years. The related solicitations are anticipated around winter 2026–2027, with service commencement anticipated in winter 2028, subject to project approval. The notice identifies an anticipated Secret-level Facility Security Clearance. Businesses that may wish to participate and do not already hold the required clearance are encouraged to review the Defence Construction Canada Industrial Security Program sponsorship process, although sponsorship does not guarantee clearance or contract award. The program may also create subcontracting, employment, and training opportunities for Indigenous businesses and communities. A business considering this opportunity should assess its northern operating capacity, relevant facilities-management experience, ability to support remote sites, subcontractor and logistics arrangements, and security-clearance requirements. This notice alone does not establish bidding requirements or confirm eligibility. Review the official notice and any future solicitation documents carefully before taking action or submitting a proposal: https://www.merx.com/public/solicitations/4083739956/abstract?language=EN. The listed closing date is November 30, 2026 at 2:00 p.m., but because this is an advance notice, confirm the current status and applicable deadlines in the official source.

Potentially relevant businesses may include Canadian AI, machine-learning, cybersecurity, compliance, enterprise-software or governance technology companies with a solution that can integrate with government enterprise systems and AI/ML lifecycle platforms. The notice specifically refers to standards-based APIs, connectors and interoperable data exchange for information such as AI-system metadata, risk assessments, compliance findings, audit evidence, monitoring results, approvals and decision records.

This summary does not establish that any company qualifies.

Department of Public Works and Government Services (PSPC) - *Canada, Gatineau, Quebec

This open tender appears relevant to businesses that provide in-water vessel cleaning with capture services, especially companies with equipment suited to different vessel coatings. The buyer is the Department of Public Works and Government Services Canada (PWGSC/PSPC), and the work would be for various Government of Canada departments and agencies on an as-needed basis. The process is a Request for Supply Arrangements (RFSA), which means it appears intended to create a list of qualified contractors by stream rather than award a single one-time contract. Key details: -Title: F7044-200268 - RFSA Refresh for In-Water Vessel Cleaning with Capture -Buyer: PSPC / PWGSC -Status: Open -Location: Canada, Gatineau, Quebec -Closing date: 2026-12-31 14:00:00 -Category: Services Plain-English summary: The government is looking for suppliers that can clean vessels while in the water and capture debris or contaminants, helping reduce the spread of aquatic invasive species and protect the marine environment. The arrangement would likely be used across multiple federal departments, and suppliers may be selected based on their proposed equipment and the vessel coating they can work with. What this may mean for a business: - Could potentially match marine service providers, environmental service firms, or contractors with specialized vessel-cleaning equipment. - The RFSA structure suggests there may be multiple suppliers approved, depending on the stream they fit. - Businesses should review the streams, technical requirements, environmental requirements, insurance, and any compliance criteria carefully.Important reminder: Please verify all details in the official tender notice and supporting documents before deciding whether to bid or submit an arrangement application, since this summary is only based on the information provided here.
