What Construction Stakeholders Need to Know About Upcoming Reforms

Introduction

Ontario's construction sector is bracing for significant legislative change as key amendments to the Construction Act will take effect on January 1, 2026.1 These updates, introduced through Bill 60 and shaped by industry feedback, will adjust lien timelines, holdback rules and contract termination requirements.

The amendments originated from an independent review by leading construction law expert Duncan Glaholt (the "Final Report")2 and address industry feedback on prior reforms.

Legislative Timeline and Implementation

Our previous article summarized the initial amendments based on the Final Report, which were introduced in November 2024 as part of omnibus budget legislation, Bill 216, Building Ontario For You Act (Budget Measures), 2024 (the "2024 Amendments").

Ontario’s Mandatory Annual Holdback Release Starts In 2027: What Owners And Contractors Need To Know

Starting in 2027, all Ontario project owners with contracts entered into on or after January 1, 2026, and most owners with contracts dating back to July 1, 2018, must start releasing statutory holdback to their contractors on an annual basis. This requirement is the latest in a series of construction payment reforms under Ontario’s Construction Act. It replaces the traditional model of retaining holdback until substantial performance. Owners and contractors who fail to comply with the notice and payment timelines face exposure to interest claims, payment disputes, and adjudication proceedings.
