About Us

Ontario Dispute Adjudication for Construction Contracts (“ODACC”) is the Authorized Nominating Authority (“ANA”) under the Construction Act. As the ANA, ODACC is responsible for administering construction-related adjudications and for training and qualifying Adjudicators.  ODACC derives its powers from the Construction Act and Ontario Regulation 306/18, accessible at the following links:

Construction Act, R.S.O. 1990 c. C.30: https://www.ontario.ca/laws/statute/90c30#BK43
