FAQ — Construction Holdback in Canada

What is construction holdback?

Holdback is a percentage of each payment that an owner withholds from a contractor until the end of the work, or until an agreed date, to secure performance. Several provinces set a statutory holdback in their construction or builders lien legislation, so check your province's act. In Quebec the Civil Code sets no percentage: it comes from the contract, and for public contracts covered by Quebec's regulation on payments and rapid dispute resolution in construction work, it is capped at 10% of the amount due and applies only if the contract provides for it.

When is holdback released?

The release date depends on your contract and on provincial lien legislation. In Quebec the Civil Code does not set a release date; do not confuse it with the 30-day period of the legal construction hypothec, which is the time to register a notice after the end of the work, not a release date for the holdback.

Is the holdback rate always 10%?

No. 10% is a statutory rate in several provinces and the maximum for covered Quebec public contracts, but in Quebec the rate for other contracts is whatever the parties wrote. Always check the holdback clause in your specific contract rather than assuming 10%.
