How to win SEAO tenders in Quebec in 2026: complete guide

What is SEAO?

The Système électronique d'appels d'offres (SEAO) is the Quebec government's official portal for publishing public contracts. Any expenditure by a public body (municipalities, schools, hospitals, Crown corporations) above certain thresholds ($101,100 for construction) must be published on it.

For a construction contractor in Quebec, SEAO means direct access to hundreds of millions of dollars in contracts every year, in every sector: civil engineering, building, electrical, plumbing, roofing, painting, snow removal and more.

The 3 challenges contractors face on SEAO

• Monitoring takes time. Manually watching SEAO takes 1 to 2 hours a day if you do not want to miss anything. Most contractors check the portal irregularly and miss opportunities.
• Deadlines are tight. A SEAO call for tenders stays open for 20 to 30 days on average. For urgent projects, it can be as little as 10 days. Every day lost lowers the quality of your bid.
• Writing the bid is complex. A SEAO bid must follow a precise format, include the right certificates (RBQ, CCQ, Revenu Québec) and respond point by point to the requirements of the specifications.

How to monitor SEAO effectively

SEAO offers email alerts by category of work (UNSPSC code). But these alerts are generic and often create noise (tenders outside your region, outside your specialty, outside your budget).

With SubmitX SEAO monitoring, you set up your criteria once:

Writing a winning SEAO bid

A public SEAO bid must contain, in addition to the price:

• A valid RBQ licence (subclass matching the work)
• A tax compliance certificate (Revenu Québec)
• A CCQ certificate if the work involves covered workers
• Proof of insurance (minimum civil liability according to the contract)
• References for similar projects (usually 3 projects in the last 5 years)
• A detailed construction schedule

How SubmitX generates your SEAO bid in a few minutes

SEAO success rates: what the numbers show

According to data from Quebec's Secrétariat du Conseil du trésor, only 27% of public calls for tenders receive more than 3 bids. Competition is therefore much weaker than you might think: the real obstacle is the ability to respond quickly and professionally.

Contractors who respond systematically (even partially) to SEAO calls for tenders have an average success rate of 1 contract for every 4 to 6 bids. At $100,000 per average contract, that is a considerable return on investment for a few hours of work.
