Government Contracts for Construction Companies in Canada

TL;DR: Construction is one of the largest government procurement categories in Canada, with 1,605 open tenders right now. Contracts range from small HVAC jobs to multi-million-dollar infrastructure. Browse construction tenders to see what's available.

Construction is consistently one of the largest categories of government spending in Canada. Federal departments, the Department of National Defence, and Crown corporations regularly tender for building construction, renovations, road and bridge work, and infrastructure maintenance.

For construction companies, government contracts offer predictable payment (the government doesn't go bankrupt) and often multi-year work. The challenge is navigating the procurement process.

Where to Find Construction Tenders in Canada

Federal Contracts

CanadaBuys is the official portal for all federal government procurement. Construction tenders are posted here alongside IT, consulting, and supply contracts. You can search by keyword or browse by GSIN commodity code.

Construction-relevant GSIN categories include:

• Y — Construction, Repair, and Maintenance of Buildings
• Z — Construction, Repair, and Maintenance of Roads, Bridges, and Infrastructure

GovBid monitors CanadaBuys daily and filters construction tenders into a browsable list, updated every morning. Each tender includes a plain-English summary, deadline, and direct link to bid.

Provincial and Municipal Contracts

Each province has its own procurement portal:

• Ontario: Ontario Tenders Portal (ontariotenders.bps.gw.supply.ca)
• British Columbia: BC Bid (bcbid.gov.bc.ca)
• Alberta: Alberta Purchasing Connection
• Quebec: SEAO (seao.ca)

Municipal contracts (cities, school boards, hospitals) are often posted on MERX, Biddingo, or the municipality's own website.

Requirements for Government Construction Work

Bonding

Most government construction contracts require three types of bonds:

1. Bid Bond — Guarantees you'll accept the contract if awarded. Typically 10% of bid price.
2. Performance Bond — Guarantees you'll complete the work. Typically 50% of contract value.
3. Labour and Material Payment Bond — Guarantees your subcontractors and suppliers get paid. Typically 50% of contract value.

If you don't already have a bonding facility with a surety company, establishing one is a prerequisite for government construction work. Start with smaller contracts (under $500K) where bonding requirements may be relaxed.

Security Clearances

Contracts on military bases or secure government facilities may require personnel security clearances. The process takes weeks to months, so apply early through the Contract Security Program administered by Public Services and Procurement Canada.

Insurance

Standard requirements include:

• Commercial General Liability ($2M+ per occurrence)
• Professional Liability (for design-build)
• Automobile Liability
• Workers' Compensation

PSAB Set-Asides

The Procurement Strategy for Aboriginal Business (PSAB) sets aside certain contracts for Indigenous-owned businesses. If your company qualifies, these set-asides reduce competition significantly.

Tips for Winning Construction Bids

1. Start with smaller contracts. Contracts under $100K or simple renovation jobs let you build a track record of government work (called "past performance") without the complexity of major infrastructure projects.

2. Visit the site. Many construction RFPs include a mandatory or optional site visit. Always attend — you'll see conditions that aren't in the drawings, and it shows the evaluator you're serious.

3. Price accurately, not aggressively. The lowest bid doesn't always win. The government evaluates "best value," which factors in your technical approach, past performance, and schedule. An unrealistically low bid raises red flags.

4. Read the specifications carefully. Government specifications are often more detailed than private-sector contracts. Materials, methods, environmental requirements, heritage building constraints — miss one and you'll blow your margin.

5. Subcontract strategically. If the RFP requires capabilities you don't have (e.g., electrical, HVAC, or specialized environmental work), line up qualified subcontractors early and include their qualifications in your bid.
