When you're managing a federal contract and need to make changes, you can't just keep amending it indefinitely. The Incremental Value Test is the principle that stops procurement officers from turning what should be a new competition into endless modifications to an existing contract. Every amendment needs to prove it adds real value and stays within the original scope. Otherwise? You're back to competitive bidding.
How It Works
The Supply Manual Chapter 5.6 on Contract Change Management is explicit about this: contract amendments must not circumvent competitive processes. Period. You're only permitted to amend if the additional work falls within the original scope and provides demonstrable value to Canada. That means you need documentation showing what value you're getting—not just convenience or avoiding the hassle of running a new procurement.
In practice, PSPC's Contract Amendments Directive sets a clear threshold: amendments exceeding 50% of the original contract value require formal justification of the added value and compliance verification with trade agreements. Ask yourself whether this change would trigger trade agreement thresholds if it were a standalone contract. For goods, that's $25,000 under CFTA; for services, it's $100,000. Cross those lines with cumulative amendments, and you're in dangerous territory.
The Treasury Board Contracting Policy reinforces this by requiring that all contract changes demonstrate best value and don't sidestep open bidding requirements. Section 32 of the Financial Administration Act provides the legal framework—your authority to amend is limited to the original purpose. Significant changes that fundamentally alter what you're buying? That's a new contract, and it needs a new competition. The test forces you to justify each modification individually and cumulatively, ensuring you're not slowly building a different contract through the back door.
Key Considerations
- Cumulative impact matters: Even if each individual amendment seems small, you need to track the total value of all changes against the original contract. Multiple 10% increases can quickly exceed that 50% threshold.
- Scope creep is your enemy: Adding related but distinct deliverables—even if they seem logical—can push you outside the original scope. If the new work wasn't reasonably contemplated in the original Statement of Work, it probably fails the test.
- Document everything: Your value assessment can't be a gut feeling. You need comparable market data, cost-benefit analysis, or clear operational justification. Auditors and oversight bodies will ask for this documentation.
- Trade agreement compliance isn't optional: Even if an amendment seems administratively simple, violating CFTA, CETA, or CUSMA thresholds through cumulative changes exposes your department to trade challenges and potential penalties.

Bottom line: when you're considering a contract amendment, apply this test rigorously. If you can't clearly articulate the incremental value and prove it's within scope, you're probably looking at a new procurement instead.
