On January 1, 2026, several anticipated amendments to the Construction Act of Ontario (“CA”) came into effect including in respect of adjudication, proper invoices, and a new mandatory annual holdback release. A lesser talked about amendment has, for the first time since 2018,[1] expanded lien rights under the CA by creating a rebuttable presumption that those who supply pre-construction design services (“Design Professionals”) to a project before construction begins, can make a lien claim if an owner retains a holdback for their services.

Public reporting indicates that construction affecting major routes may be limited between May and July 2026, with some projects being sequenced or temporarily paused to accommodate traffic management and event logistics, creating foreseeable, non-project-specific constraints.

Sayers Foods Ltd. v. Gay Company Ltd., 2026 ONSC 918, is not only the latest notable Divisional Court pronouncement on statutory adjudication, but it also addresses matters of general importance beyond the Construction Act: allegations of fraud, delay claims, adjudicator bias and the treatment of evidence on judicial review.
