Ontario’s Construction Payment Dispute Resolution Process

As of October 1, 2019, a new method for resolving construction payment disputes came into effect with the creation of Ontario Dispute Adjudication for Construction Contracts (ODACC) under Ontario’s Construction Act. The aim of ODACC is to facilitate a more efficient and streamlined process for resolving matters involving payment under a construction contract. There are often multiple tiers of service providers affected by non-payment or delays, and so it is crucial to resolve these matters quickly. Adjudicating these matters through ODACC is a mandatory step in resolving a payment issue, and will often serve as a final resolution, however, parties do reserve the right to appeal a decision through arbitration or litigation.

At Tierney Stauffer LLP, we will help clients navigate the ODACC adjudication process, and will pursue an appeal of any ODACC decision through alternative dispute resolution or in court, as necessary.
