Where does the City of Hamilton post its tenders?

The City of Hamilton posts its bid opportunities on its bids&tenders portal at hamilton.bidsandtenders.ca, where you review, register for, and submit bids online. CityHousing Hamilton's social-housing work now posts on that same City portal — it retired its standalone site — so it appears in the same feed.

Do I have to pay to bid on City of Hamilton work?

A free account lets you browse opportunities and receive email bid alerts by commodity code. To become a registered plan taker and submit a bid, the portal charges a fee — either an ongoing subscription or a one-time, single-opportunity option. Confirm the current options on the portal before you bid.

At what dollar value does Hamilton run an open tender?

Under the City's procurement by-law (20-205, updated through 2025), construction from $10,000 up to $334,400 is handled as a Request for Quotations, and construction at $334,400 or more is posted as a Request for Tenders awarded to the lowest compliant bid. For goods and services, the open-tender threshold is $133,800. Always confirm against the current by-law.

How to find and win government tenders in Hamilton (2026)

Where the City of Hamilton posts construction tenders — its bids&tenders portal — plus the bid thresholds in its procurement by-law, the Ontario and federal layers, and how Ontario's prompt-payment rules affect you.

Hamilton runs its tenders through a single City portal, with a procurement by-law that spells out exactly when a job goes to open tender. Layer Ontario's provincial portal and prompt-payment rules on top, and "how to bid in Hamilton" is a fairly defined path. Here's where the work is posted and what it takes to win it.

Where Hamilton posts its tenders

The City of Hamilton posts bid opportunities — tenders, RFPs, and RFQs — on its bids&tenders portal at hamilton.bidsandtenders.ca. You review opportunities, register, and submit your bid there electronically.

One thing to know: CityHousing Hamilton — the city's social-housing provider — used to run its own bids&tenders site, but it has consolidated onto the City's main portal. Its social-housing construction and maintenance work now appears alongside everything else on hamilton.bidsandtenders.ca.

Two further streams matter:

Provincial work posts on the Ontario Tenders Portal, operated by Supply Ontario — the official provincial procurement site. Registration is free.
Federal work in the Hamilton region posts on CanadaBuys.

What triggers an open tender

Hamilton's procurement by-law (20-205, updated through 2025) sets clear dollar bands. For construction:

$10,000 up to $334,400 — handled as a Request for Quotations (RFQ), with the department obtaining quotes from multiple suppliers.
$334,400 or more — posted as a Request for Tenders (RFT) on the portal, awarded to the lowest compliant bid.

For goods and services the open-tender threshold is $133,800, and a Request for Proposals (RFP) is used from $10,000 when the requirement can't be fully specified up front. If you're unsure which process applies, our guide to the tender types explains RFQ vs RFT vs RFP.

Who's buying

The City's heaviest construction spend runs through Public Works: water, wastewater, and stormwater infrastructure; roads and bridges; and transit (the HSR), including a major bus maintenance facility. The City also publishes a capital-projects view for pipeline scouting. Provincial ministries and broader-public-sector bodies, plus federal facilities in the region, add the institutional layers.

How to register and bid

Create an account on hamilton.bidsandtenders.ca. A free account lets you browse and receive bid alerts by commodity code; becoming a plan taker to submit a bid carries a fee — either a subscription or a one-time, single-opportunity option. Check the current choices on the portal.
Register on the Ontario Tenders Portal (free) for provincial work, and see our CanadaBuys guide for contractors for the federal stream.
Read each solicitation in full and ask questions before the deadline — Hamilton communicates the deficiencies that make a bid non-compliant, and compliance is where most public bids are lost.

What it takes to win — and to get paid

A complete, responsive submission. Tenders here are awarded to the lowest compliant bid; an incomplete package is set aside regardless of price. Our go/no-go framework helps you spend effort on the bids you can actually win.
Bonding and insurance scale with project size; larger work requires performance and labour-and-material payment bonds.
Prompt payment is law in Ontario. Under the Construction Act, an owner must pay a proper invoice within 28 days or issue a notice of non-payment within 14, and you must pay your subcontractors within 7 days of being paid. Disputes can go to interim adjudication through ODACC, and further amendments took effect January 1, 2026 — worth knowing your rights before a payment stalls.

A single City portal helps, but you still sort Hamilton work from provincial and federal noise across separate sites — and you still draft every proposal from scratch. Cornerstone Contracts scans the portals that carry Hamilton work every day, scores each posting against your trade, region, and project size, and drafts a compliance-aware proposal for any tender you want to pursue. Start free to see your matched Hamilton opportunities in one feed.

Portal coverage, fees, thresholds, and procurement rules change. Confirm current details on each provider's site and follow the requirements of the specific solicitation you're bidding.
