Bid Bonds vs. Performance Bonds: Essential Knowledge for Every Contractor

In the fast-paced world of Ontario construction, your ability to bid and win contracts often comes down to more than just your price and experience. It's about your credibility. If you’re targeting public contracts or large-scale private developments, you've likely encountered requirements for Bid Bonds and Performance Bonds.

At Roughley, we believe insurance doesn’t have to be complicated. Part of making it better is ensuring you have the Roughley Advantage—the expert knowledge you need to navigate these requirements so you can focus on building.

Here is everything you need to know about the difference between these two critical financial tools.

The Big Picture: What’s the Difference?

While both are types of surety bonds, they kick in at different stages of your project. Think of it this way: a Bid Bond gets you in the room, while a Performance Bond keeps you there until the job is done.

1. Bid Bonds: The "I’m Serious" Guarantee

A Bid Bond is submitted during the tender phase. It provides a financial guarantee to the project owner (the obligee) that if you win the contract, you will actually sign it and provide the required final bonds.

• When it's needed: At the time of bid submission.
• What it covers: Usually 5% to 10% of your total bid value.
• The risk: If you win but refuse to sign the contract (perhaps because you realized you underbid), the bond pays the owner the price difference to hire the next lowest bidder.

2. Performance Bonds: The "I’ll Finish" Guarantee

Once you've won the contract, the Bid Bond is typically replaced by a Performance Bond. This is your promise that you will complete the work according to the specific terms, standards, and timelines in the contract.

• When it's needed: Shortly after the contract is awarded (usually within 10 days).
• What it covers: Typically 50% or 100% of the total contract value.
• The risk: If you default on the project (due to insolvency, mismanagement, etc.), the surety steps in to find a new contractor or compensate the owner for the cost to complete the project.

Why Contractors Need Both in 2026

The landscape for Ontario contractors is becoming more regulated. Under the Ontario Construction Act, surety bonds are no longer just nice-to-haves for large projects.

• Public Contract Mandates: Section 85.1 of the Act requires that all public contracts (for the Crown, municipalities, or public sector organizations) with a price of $500,000 or more must have a performance bond and a labor and materials payment bond.
• Competitive Edge: Even on private projects where bonds aren't legally mandated, having a bonding facility signals to owners that a third party has "pre-qualified" your financial and operational capacity. This makes you a much more attractive—and lower-risk—partner.
