Ontario Construction Lien FAQs

Is this legal advice?

No. BuilderLien tracks deadlines and ensures you have time to seek proper legal advice. We're not lawyers, we're deadline guardians. Always verify your obligations with a construction lawyer before taking action.

What if your calculations are wrong?

BuilderLien calculations are based on Ontario's Construction Act as updated for 2026. However, construction law is complex, and every project is unique. We recommend always verifying critical deadlines with a construction lawyer who specializes in your project type. BuilderLien is a tool to help you stay organized, not a replacement for legal counsel.

What if I enter wrong dates?

You can edit your project dates anytime, and all deadlines will recalculate automatically. We recommend double-checking your project start date (the most critical input) against your contract and project documents before finalizing. BuilderLien alerts you as a safety net—not as your only safeguard.

What are the new Ontario annual holdback rules for 2026?

As of January 1, 2026, Ontario's Construction Act requires annual holdback release through a cascade process: contract anniversary triggers the process, owner publishes notice within 14 days, owner pays holdback 60-74 days after notice, and general contractor pays subcontractors within 14 days. BuilderLien tracks every deadline in this cascade automatically.

How does the 14-day holdback notice work under the 2026 Construction Act?

Within 14 days of your contract anniversary, the project owner must publish a notice of intended holdback release. This notice starts the 60-74 day payment window. Missing this deadline affects the payment timeline, but your lien rights remain intact under the 2026 rules.

When do the 2026 holdback rules apply to existing contracts?

For contracts signed before January 1, 2026, the first mandatory annual holdback release occurs on the second anniversary after January 1, 2026. This transition rule gives existing projects time to adjust to the new requirements.

Do lien rights expire automatically under Ontario's 2026 Construction Act?

No. Bill 60 originally proposed automatic lien expiration, but this provision was scrapped. Under the current 2026 rules, your lien rights remain intact and do not expire automatically. You still need to preserve and perfect your lien within existing timeframes.

Does BuilderLien track the new 2026 annual holdback deadlines?

Yes. BuilderLien automatically calculates every deadline in the 2026 annual holdback cascade, including contract anniversary dates, 14-day notice windows, 60-74 day payment periods, and subcontractor payment deadlines. You'll receive alerts 7, 3, and 1 day before each deadline.
