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.

Cleared For Investment: Canada Opens The Door To Private Capital At Its Largest Airports

A Matter Of Interpretation: Termination Clause Prevails Under The Canada Labour Code

The Ontario Superior Court of Justice has applied the Baker v. Van Dolder's Home Team framework to uphold a termination clause under the Canada Labour Code, rejecting a plaintiff's claim for common law reasonable notice. This decision demonstrates how courts will now interpret employment agreements by examining the parties' objective intentions rather than conducting technical word-by-word analysis of contractual provisions.
