Construction Law Reform: Prompt payment, adjudication, and modernization

Alberta's Prompt Payment and Construction Lien Act


The Government of Alberta's new Prompt Payment and Construction Lien Act is now in effect, replacing the former Builders' Lien Act. The framework establishes strict timelines and rules for payments, revises some key aspects of the existing lien legislation and creates a new adjudication framework for payment disputes within the construction industry.

These changes could have a profound impact on Alberta's construction industry. From payment due dates, holdback requirements, and lien periods, to fast-track adjudication as an alternative dispute process during the life of the contract, the reforms have the potential to change the way those in the construction industry do business.
