Ontario Construction Act – the Interim Adjudication Regime

 In Construction Law

Significant changes to Ontario’s Construction Act were made in 2019, and many of them had the goal of preventing delays in construction projects. Because of the typical “tiered” structure in construction projects (with layers of participants, descending from the owner to the general contractor to contractors and subcontractors), relatively minor disputes at one level have the potential to disrupt an entire project, with a significant impact on all of the participants.

To reduce this risk, the Construction Act was amended to include an adjudication system to address interim disputes between participants without disrupting or delaying a project. This approach was modeled off of one first introduced in the UK. The interim adjudication process is essentially a streamlined version of arbitration, the crucial difference being that the determination of the interim adjudicator will not be permanently binding on the parties.

The purpose of the adjudication process is to achieve an interim solution to allow work on the project to continue. Unlike the main construction lien regime, adjudication is to be utilized while a contract is still underway, not after it is concluded. Any party dissatisfied with an adjudicator’s determination can later bring a court action or application, or pursue a full arbitration, to address the same issue. The determination of the interim adjudicator will not necessarily have any bearing on the outcome of that later process.

The types of issues that can be addressed by an interim adjudicator include: the value of services or materials; payments under contracts or change orders; amounts retained as set-offs by trustees or as lien set-offs; payment or non-payment of holdbacks; and any other matter which the parties agree to adjudicate. To commence an adjudication, one party can give someone they have contracted with a written notice setting out:

  • the names and addresses of the parties;
  • the nature of the dispute, with some details as to how it arose;
  • the relief being sought; and
  • the name of a proposed adjudicator.

Once the process has been commenced, there are strict timelines to ensure that an interim determination can be made in thirty-nine to forty-six days. An adjudicator has four days to accept or decline their appointment after the written notice is issued, and if they decline then the Authorized Nominating Authority (currently ODACC) has seven days to select another adjudicator. Once the adjudicator is set, the party requesting adjudication has five days to provide documents supporting their complaint to the adjudicator, after which time the adjudicator has thirty days to issue a determination. There is a provision for an adjudicator to request the parties’ consent for an additional fourteen days of time in which to issue a determination.

In the course of making a determination, an adjudicator is empowered to: make directions respecting the conduct of the adjudication; take the initiative in ascertaining relevant facts and law; draw inferences based on the parties’ conduct; conduct an onsite inspection; and to attain the assistance of other experts. Usually, the parties will share the expense of the adjudicator, but the adjudicator can order costs against one party if they acted in a way that was frivolous, vexatious, or an abuse of process. An adjudicator’s determination becomes enforceable by way of an Application to the court for an Order enforcing the determination.

Once a determination has been made, parties can only attempt judicial review in narrow circumstances. Even if a party does seek a judicial review of the determination, the determination remains in force until a court orders otherwise.

The interim regime gives significant discretion to adjudicators, as well as broad powers. The whole purpose of the regime is to have someone who can quickly and decisively address a dispute so that the construction project can continue without being delayed – with the caveat that an adjudicator’s determination truly is “interim”, and the same issue is wholly subject to being re-litigated at a later date.

While it is not necessary for parties to an interim dispute before an adjudicator to be represented by counsel, such parties can still benefit from legal advice while navigating the interim adjudication process.
