On October 1, 2019, Bill 142, the Construction Lien Amendment Act¹ came into force amending the Construction Act² and introducing a prompt payment and an adjudication regime in Ontario. Ontario is the first jurisdiction in Canada to have legislation that combines prompt payment and adjudication alongside traditional lien legislation. Borrowing from the long-standing UK model, the Construction Act now includes a procedure for prompt payment, and a comprehensive adjudication procedure. In Ontario, the Authorized Nominating Authority under the Construction Act is ODACC, and several hundred adjudications have been heard since the prompt payment provisions came into force.
