Notice of suspension of work

A notice of suspension of work is the written notice a contractor gives to stop performing the work under a construction contract. In the standard Canadian stipulated-price contract, CCDC 2 – 2020, that right lives in GC 7.2 – Contractor's Right to Suspend the Work or Terminate the Contract: the contractor gives the owner Notice in Writing that the owner is in default, warns that the work will be suspended if the default is not corrected within 5 Working Days, and may then suspend the work — or terminate the contract outright.

How GC 7.2 works

Under GC 7.2.3, the contractor may give Notice in Writing to the Owner (with a copy to the Consultant) that the Owner is in default of the Owner's contractual obligations if:

.1 the owner fails to furnish reasonable evidence that financial arrangements have been made to fulfill its obligations under the contract;
.2 the Consultant fails to issue a certificate as provided in Part 5 of the General Conditions – Payment;
.3 the owner fails to pay the contractor, when due, the amounts certified by the Consultant or awarded by adjudication, arbitration or court; or
.4 the owner fails to comply with the requirements of the contract to a substantial degree, and the Consultant gives a written statement detailing that failure (with one financing-information exception).

GC 7.2.4 then sets the mechanics: the notice must advise that if the default is not corrected within 5 Working Days after receipt, the contractor may, without prejudice to any other right or remedy, suspend the Work or terminate the Contract. If the contractor terminates under these conditions, GC 7.2.5 entitles it to payment for all work performed including reasonable profit, loss on products and construction equipment, and other damages resulting from the termination.

Suspension ordered by others

Court or public-authority stop-work orders

Where the work is halted by an order of a court or other public authority — not the contractor's fault — GC 6.5.2 entitles the contractor to an extension of the Contract Time and reimbursement of reasonable costs incurred as a result of the delay. Separately, GC 7.2.2 gives the contractor a termination right where the work is suspended or otherwise delayed for 20 Working Days or more under such an order.

Delay notices generally

Time-extension claims have their own notice discipline: GC 6.5.4 requires Notice in Writing of the cause of delay to the Consultant no later than 10 Working Days after the delay commences (one notice suffices for a continuing cause). Missing that window can forfeit the extension.

Why it matters for suppliers

It is leverage, not a first move

The suspension right exists to make non-payment or substantial non-compliance self-correcting: the 5-Working-Day cure period gives the owner a final chance before work stops and costs start compounding. Contractors should document the default precisely — certified amounts due, dates, the consultant's statements — because an unsupported suspension notice can itself put the contractor in breach.

Public-sector owners feel it quickly

For government buyers, a contractor suspension on a bonded public project implicates the performance bond, the surety, and the project schedule simultaneously. Resolving the underlying payment default before the cure period expires is almost always cheaper than the alternative.

Common questions

Can the owner suspend the work?

CCDC 2 – 2020 has no standalone owner-suspension clause; owners direct changes through Change Orders and Change Directives (GC 6.1–6.3), and third-party stop-work orders are handled through the GC 6.5 delay provisions. Supplementary conditions sometimes add owner suspension rights — always read the project's supplementary conditions.

Does a suspension notice end the contract?

No. Suspending the work pauses performance while the contract stays alive; termination ends it. GC 7.2 lets the contractor choose between the two once the cure period lapses, and the choice has very different legal consequences.
