How to bid on hvac & plumbing contracts in Québec

29 hvac & plumbing tenders open in Québec right now, from 25 public buyers.

1. Where Québec posts hvac & plumbing tenders

Québec public buyers post hvac & plumbing solicitations on SEAO (Système électronique d'appel d'offres) and increasingly on national platforms like CanadaBuys. Municipal buyers in Québec may also use Biddingo or BidsAndTenders. Checking each portal daily is how opportunities get missed — a single aggregated feed solves it.

2. What documents you need

Most Québec hvac & plumbing solicitations require: proof of insurance (typically $2M+ liability), WSIB or provincial workers' compensation clearance, relevant trade certifications and licenses, and references from comparable public work. Federal buyers add security clearance requirements. Read the full RFP — requirements buried on page 40 disqualify more bidders than pricing does.

3. Never miss a deadline

The next hvac & plumbing deadline in Québec closes 2026-10-06. Deadlines cluster at month-end and quarter-end. A weekly digest with your trade and province pre-filtered catches everything without daily portal-checking.

4. How hvac & plumbing contracts are valued

Public buyers in Québec follow procurement thresholds: smaller purchases may use simplified quotes, while larger hvac & plumbing projects require formal RFPs with published evaluation criteria. Winning bids typically price 5–15% below the engineers' estimate on construction-adjacent work.
