Prompt payment rules for construction industry

Prompt payment rules establish payment timelines and an adjudication process for contractors and subcontractors.

ARCANA AB has been selected as the first Nominating Authority under the Prompt Payment and Construction Lien Act (PPCLA). ARCANA AB is authorized by the Minister of Service Alberta and Red Tape Reduction to appoint an adjudicator to settle late payment disputes between contractors when they are not able to settle it on their own. Learn more about Resolving disputes.

Prompt Payment rules are in force as of August 29, 2022.


The construction industry is a multi-billion dollar sector of Alberta’s economy that creates thousands of jobs for Albertans.

Payment timelines for Alberta’s construction industry, along with timelines for filing liens and rules for adjudication in the event of a payment dispute, are outlined in the Prompt Payment and Construction Lien Act, the Prompt Payment and Adjudication Regulation, and the Prompt Payment and Construction Lien Forms Regulation.

All new construction contracts in Alberta must adhere to the rules of the Prompt Payment and Construction Lien Act as of August 29, 2022.

Existing contracts that are scheduled to end before August 29, 2024 do not need to be changed to adhere to the new rules. Existing contracts that extend beyond August 29, 2024 have to become compliant by August 29, 2024.

Prompt payment rules

  • Affected parties

    Prompt payment rules apply to contractors, subcontractors, labourers, and regulated professional engineers and architects who provide materials or consultative services, or who work on construction projects. The new rules apply to construction projects, materials, and work covered previously by the Builders’ Lien Act.

    Alberta government project contracts are subject to the Public Works Act. Rules and are exempt from timelines outlined in the Prompt Payment and Construction Lien Act.

  • Payment timelines

    Project owner to contractor

    Project owners must pay the amount payable to contractors within 28 calendar days of receiving a proper invoice (see Billing and invoices below).

    If a project owner disputes an invoice, they must give notice to the contractor within 14 calendar days of receiving the invoice. Once a Notice of Non-Payment is provided, a project owner may withhold payment of all or a portion of the amount invoiced. A Notice of Non-Payment must include the amount that is being withheld, and the reasons for non-payment.

    Contractors to subcontractors

    Contractors must pay each subcontractor the amount owed within 7 calendar days of receiving payment from the owner. If a subcontractor has not received payment within the required timeline, they may issue a Notice of Adjudication to initiate an adjudication process. Notice of Adjudication forms are available from Nominating Authorities.

  • Billing and invoices

    Proper invoices

    A proper invoice is a written bill or other request for payment of the work done or materials provided under a construction contract.

    Proper invoices must contain all of the following:

    • Contractor’s name and business address
    • Date of the invoice
    • The period during the work was done or materials were provided
    • A description of the work done or materials provided
    • Amount requested for payment
    • Payment terms, broken down for the work done or materials provided
    • Name, title, and contact information of the person to be paid
    • A statement indicating that the invoice provided is intended to be a proper invoice

    Proper invoices may be revised if the:

    • Parties to the invoice agree to a revision,
    • Date of the proper invoice is not changed, and
    • Proper invoice continues to meet the requirements
  • Holdbacks

    Projects that have a minimum $10 million contract value and exceed 12 months in duration will be able to utilize new rules that allow for quicker release of holdbacks.

    Unless the contract allows for progressive or phased releases, holdbacks will be released annually. Phased or progressive holdbacks must be less than one year. The contract must clearly define the phases and if there is any ambiguity, the annual release will apply.

    This will ensure that holdbacks are not held for more than one year on a multi-year large scale project.

    These new rules will apply to any contracts executed after August 29, 2022. Existing contracts that are scheduled to end before August 29, 2024 do not need to be changed to adhere to new rules. Existing contracts that extend beyond August 29, 2024 will have 2 years to become compliant.

  • Liens

    A builders’ lien gives contractors, subcontractors, suppliers, and labourers a way to collect money owed to them for labour and materials used to improve the land, including work on any structures on the land.

    Information about how to file a lien, along with timelines for filing, is available on the Register a land title document or plan page.

Resolving disputes

If a dispute arises regarding work performed under a construction contract, parties to the contract may initiate an adjudication process to resolve the dispute.

Adjudicators are certified and trained through Nominating Authorities. The Government of Alberta authorizes organizations to serve as Nominating Authorities through an open procurement process.

At the time the contract is signed, project owners and contractors can choose the Nominating Authority that they would prefer to work with in the event of a dispute.

Currently, there is one Nominating Authority in place, ARCANA AB. To learn more about Nominating Authorities, or to contact ARCANA AB, visit ‘Nominating Authorities’ information below.

  • Adjudication process

    Provided they have not already initiated a court application about a dispute, contractors and subcontractors may submit a notice for adjudication for disputes regarding:

    • valuation of services or materials provided under the contract or subcontract
    • payment
    • notices of non-payment
    • payment or non-payment of an amount retained as a lien
    • any other matter in relation to the contract or subcontract that the parties in dispute agree to
  • Nominating Authorities

    In April 2023, ARCANA (AB) was designated as a nominating authority under the Prompt Payment and Construction Lien Act. This means that they will have the power to nominate adjudicators to resolve disputes under the act.

    • certifying and training adjudicators for disputes
