Notice of Non-Payment in Saskatchewan
Under the Builders' Lien Act (Prompt Payment Amendment), SS 1984-85-86, c. B-7.1 (am. SS 2019, c. 2)
A notice of non-payment is the only way a payer can refuse, in whole or in part, to pay a proper invoice in Saskatchewan without losing the dispute. It must be delivered within 14 days (SK Builders' Lien Act s. 5.4(2)) and must give the specific reasons for non-payment.
One of the forms carries a mandatory undertaking to refer the dispute to adjudication within 21 days (SK Builders' Lien Act s. 5.5(5)(c)).

The Saskatchewan dispute window is 14 days
The notice-of-non-payment window in Saskatchewan is shorter than the owner-payment window. A notice delivered after the 14-day window closes (SK Builders' Lien Act s. 5.4(2)) is generally treated as no notice at all, and the invoiced amount becomes payable in full.
The forms and the undertaking to adjudicate
Saskatchewan follows the Ontario family of notice forms: one from an owner to a contractor, one from a contractor to a subcontractor when the owner has paid, and one when the owner has not.
When a contractor withholds payment from a subcontractor because the owner has not paid, the notice must include an undertaking to refer the dispute to adjudication within 21 days (SK Builders' Lien Act s. 5.5(5)(c)). Tiercord branches to the correct form automatically and enforces that undertaking where it applies.
Reasons must be specific
A valid Saskatchewan notice states the amount being withheld and the specific reasons for non-payment. Vague or boilerplate reasons can render the notice ineffective, so the wording matters as much as the timing.
