When the federal government pays contractors for work, it doesn't always hand over the full amount right away. A retention holdback is money withheld from progress payments—typically 5-10% of each payment—until the contractor fully delivers on their obligations. This gives the Crown financial security to ensure performance and fix any deficiencies that emerge.
How It Works
The Supply Manual treats holdbacks as a risk management tool. According to Section 6.50.5, the percentage and duration aren't fixed across all contracts. Instead, you determine them based on an assessment of the risks involved, the complexity of the work, and whether provincial or territorial lien legislation applies. For construction contracts especially, lien laws often drive the holdback structure.
In federal construction work, you'll almost always see a 10% holdback. PSPC's standard terms (SACC R2810D GC5.5) specify that 10% gets retained from each progress payment as required by applicable lien legislation. That money sits there until two conditions are met: the work is satisfactorily completed, and the statutory lien period under provincial or territorial law has expired without any liens being registered. In practice, this means contractors might wait 45 to 60 days after substantial completion before seeing their holdback released, depending on which province's Construction Lien Act applies.
The contract must spell out the holdback terms clearly—Supply Manual Section 6.50.1 is explicit about this. You need to state the percentage retained, how it's calculated (usually as a percentage of each progress payment), and the exact conditions for release. Those conditions might include final acceptance of deliverables, expiry of warranty periods, correction of deficiencies identified during inspections, or satisfaction of lien statute requirements. The Treasury Board's Directive on Payments reinforces that these terms can't be vague or arbitrary; they must align with legislation and policy.
Key Considerations
- Provincial lien laws govern construction holdbacks: Even though you're working under federal contracts, provincial and territorial construction lien legislation determines the mandatory holdback percentage and release timing for construction work. You can't simply ignore Ontario's Construction Act or BC's Builders Lien Act because you're contracting with PSPC.
- Holdbacks aren't just for construction: While 10% construction holdbacks are standard, you can apply retention holdbacks to IT projects, consulting contracts, or any procurement where you need security against non-performance. The percentage and release conditions should match the risk profile—maybe 5% held until final acceptance and warranty expiry on a complex IT implementation.
- Release isn't automatic: Contractors sometimes assume the holdback gets released immediately after they finish the work. It doesn't. You need to verify that all contract requirements are met, the lien period has expired, deficiencies are corrected, and any warranty obligations are clearly documented before authorizing release.
- Cash flow impact on smaller contractors: A 10% holdback on a multi-million dollar construction project represents significant working capital tied up for weeks or months. Smaller contractors may struggle with this, which is why clear communication about release timelines matters for maintaining a healthy supplier relationship.

The bottom line? Retention holdbacks protect your department's interests, but they need to be carefully structured in the contract and administered consistently with both federal policy and applicable provincial legislation.
