Should my Ottawa driveway contract reference Ontario lien holdback?

Yes, your Ottawa driveway contract should reference Ontario lien holdback requirements. Under Ontario's Construction Act, homeowners must hold back 10 percent of the contract value for 45 days after substantial completion to protect against potential construction liens from unpaid subcontractors or suppliers.

How Ontario Lien Holdback Works for Driveways

The Construction Act applies to all construction projects in Ontario, including residential driveways. When you hire a paving contractor, that contractor may use subcontractors (excavation crews, base material suppliers, asphalt plants, equipment rental companies) who have lien rights against your property if they're not paid by the general contractor. The 10 percent holdback protects you by ensuring funds are available to satisfy any valid liens.

For example, on a $8,000 asphalt driveway project, you would pay $7,200 upon substantial completion and hold back $800 for 45 days. If no liens are filed during that period, you release the holdback to the contractor. If liens are filed, the holdback funds can be used to pay valid claims, protecting your property from lien enforcement.

Ottawa-Specific Considerations

Many Ottawa driveway contractors work with the same trusted suppliers repeatedly — local asphalt plants like Lafarge or Miller Paving, aggregate suppliers, and equipment rental companies. Established contractors typically have good payment relationships and rarely face lien issues. However, newer contractors or those experiencing cash flow problems may delay paying suppliers, creating lien risk for homeowners.

The holdback requirement is particularly important for larger Ottawa driveway projects ($15,000+) involving multiple trades — heated driveway systems requiring electrical and plumbing work, extensive excavation and drainage, or projects requiring permits and City of Ottawa inspections. These complex projects involve more subcontractors and suppliers, increasing potential lien exposure.

Contract Language and Practical Steps

Your driveway contract should clearly state: "This contract is subject to the holdback provisions of Ontario's Construction Act. The owner will retain 10% of the contract price for 45 days following substantial completion." The contract should define what constitutes substantial completion — typically when the driveway is fully paved, compacted, and ready for use, even if minor cleanup remains.

Reputable Ottawa paving contractors understand and expect lien holdback. Be wary of contractors who refuse to include holdback provisions or demand full payment upfront — this often indicates cash flow problems or unfamiliarity with proper construction practices. Never pay more than 90 percent until the holdback period expires.

When to Hire a Pro

For driveway contracts over $10,000 or involving multiple trades, consider having a construction lawyer review the contract language. The Ottawa Construction Network can help you find contractors familiar with proper lien holdback procedures and Construction Act compliance.
