How to bid on Quebec government contracts (2026)

Quebec runs one of the largest public construction programs in Canada — provincial infrastructure, transport, health and education facilities, Hydro-Québec, and municipal work across every region. In 2025 alone, Quebec public bodies published well over 50,000 tenders. The opportunity is real; the friction is that Quebec's process has its own portal and its own rules, and most guides written for the rest of Canada skip them.

Here's how Quebec public work actually gets posted, and what it takes to be eligible to win it.

Where Quebec posts its tenders

Almost everything runs through SEAO — the Système électronique d'appel d'offres, at seao.ca. Unlike the rest of the country, where opportunities are scattered across competing portals, Quebec mandates a single one: provincial ministries, Crown corporations, the health and social-services network, education and higher-education institutions, and municipalities are all required to publish their notices, distribute their tender documents, and report their awarded contracts through SEAO.

Two other streams still matter:

• Construction notices frequently mirror to MERX, so a tender you find there usually points back to SEAO to actually bid.
• Federal work located in Quebec — federal buildings, ports, Parks Canada sites — posts on CanadaBuys. See our plain-English guide to CanadaBuys.

Who's buying

The volume comes from a few large layers:

• Provincial ministries and agencies — the Ministère des Transports for roads and structures, and the Société québécoise des infrastructures (SQI), which manages most government buildings.
• The health network (CISSS and CIUSSS) and education (centres de services scolaires, cégeps, and universities) — large, steady institutional construction and renovation.
• Hydro-Québec for its capital and maintenance program.
• Municipalities, led by the Ville de Montréal and the Ville de Québec. If you work in and around Montréal, start with our Montréal government tenders guide.

How to register and bid on SEAO

Browsing notices on SEAO is free — you can see what's open without an account. To go further you register an enterprise (entreprise) profile at seao.ca:

• A paid subscription unlocks the full tender documents, electronic bid submission, and personalized notifications for the categories you serve. Browsing is free; bidding is not.
• Most solicitations are submitted electronically through SEAO before the closing time. The median bid window is about 30 days, but shorter ones are common — register and get your documents early.
• Quebec public procurement is conducted in French: the notices, the documents, and your bid will be in French. Budget for that if your firm operates primarily in English.

The Quebec-specific requirements that decide eligibility

This is where Quebec differs most from Alberta, BC, or Ontario. Three things gate who can even submit:

• RBQ licence. Under the Building Act, any contractor doing construction work in Quebec must hold a licence in good standing from the Régie du bâtiment du Québec. The RBQ verifies your competence, solvency, and financial probity — allow weeks, not days.
• AMP authorization to contract. For larger public contracts (broadly $5M+ for construction, $1M+ for services, and lower thresholds for the City of Montréal), you must hold an authorization from the Autorité des marchés publics on the date you submit your bid. As of April 2, 2026 these authorizations no longer carry an expiry date, but the annual update obligation remains.
• Revenu Québec attestation. Public contracts above a set value commonly require a valid attestation de Revenu Québec confirming your tax filings are in order — confirm the threshold in each tender's documents.

What it takes to win

Eligibility gets you to the table; a disciplined bid wins it:

• Get your RBQ licence and (where required) AMP authorization in place before the tender you want, not during it. Missing either makes an otherwise strong bid non-compliant.
• Bonding and insurance scale with project size, the same as the rest of Canada.
• A complete, responsive, French-language submission. The most common reason capable contractors lose winnable Quebec work is a rushed or non-conforming response — not price.

The broader mechanics that apply across the country — bid types, trade agreements, and go/no-go discipline — are covered in why contractors lose government bids and the RFQ vs ITT vs RFP explainer.
