A public tender comes across your desk.
The scope fits. The crew is available. The pricing looks realistic. The project is the kind of opportunity that could move your business into larger public work.
Then one number changes the conversation.
$500,000.
In Ontario, public construction contracts at or above this threshold can trigger prescribed bonding requirements, including performance bonds and labour and material payment bonds.
That means the tender is no longer just asking whether you can build the job. It is asking whether your business is ready to be backed by the surety market.

The Job May Fit. The Bond File May Not.
Many contractors think about bonding too late.
The estimator is finalizing numbers. The bid deadline is approaching. The project looks like a strong fit. Then the contractor realizes the tender requires bonds, and the surety needs more than a quick request.
A surety may need to review:
- Current financial statements
- Interim financials
- A work-in-progress schedule
- Backlog details
- Bank information
- Comparable project history
- Explanations for any problem jobs, underbillings, or margin fade
That is where capable contractors can get caught.
Not because they cannot perform the work, but because their bond file is not ready when the tender arrives.
Why This Matters Before You Bid
A $620,000 public project may not feel like a major leap for a growing contractor. The crew may be ready. The schedule may make sense. The scope may be familiar.
But surety does not evaluate only the project. It evaluates the business behind the project.
The surety wants to understand whether the contractor has:
- Financial strength
- Reporting discipline
- Working capital
- Backlog control
- Project history
- The ability to complete the work without putting the business under pressure
That review cannot always happen cleanly at the last minute. If the file is incomplete, unclear, or rushed, the opportunity can become difficult to pursue before pricing even matters.
The Real Risk Is Missing the Opportunity
The real cost of poor bond readiness is not always the bond premium.
It is the missed tender.
It is the public project that looked achievable but could not be supported in time. It is the growth opportunity that exposed a gap the contractor did not know existed.
That is why bonding should not be treated as paperwork. It should be part of the contractor’s growth plan.
Before pursuing larger public or bonded work, contractors should know:
- Their current single-job limit
- Their aggregate bonding capacity
- Whether their financial package is current
- Whether their WIP schedule tells a clear story
- What documentation gaps may slow the file down
- What the surety market is likely to question

We created The $500,000 Threshold: A Contractor Bonding Readiness Brief for Ontario contractors who want to pursue public or larger bonded projects without being blindsided at the deadline.
The brief walks through a practical contractor scenario and shows how a job that looks achievable can become difficult to bid when the bonding file is not ready.
Inside the brief, contractors will find guidance on:
- Why the $500,000 threshold matters
- What sureties look for before supporting a bonded job
- How incomplete files can slow down a tender opportunity
- What to review before the next public tender appears
- How financial readiness, WIP reporting, facility limits, and surety expectations connect

Final Thought
The best time to think about construction bonding is not when the tender is due.
It is before the opportunity appears.
Because once the $500,000 threshold is crossed, the bid is no longer just about the work. It is about whether your business is ready to be backed.
