D-0006 · Natural Resources Canada publishes 1,859 contract amendment rows that depart from the schema
28 September 2026 · Natural Resources Canada
Obligation. The dataset Proactive Publication of Contracts is published with a schema. For the field amendment_value the schema reads: “it is recommended that the contract amendment value be the value of the contract amendment”. Its check on the same field reads: “This field must be populated if Amendment (A) was selected as the Instrument Type”. For the field contract_date it reads: “It is recommended that the contract date for an amended contract or the exercising of an option be the date that the contract is awarded (or the hard commitment date)”. The Directive on the Management of Procurement, Appendix C, section C.2.2, requires the published data to be “materially accurate and complete”.
Conduct. The dataset, as downloaded on 2 September 2026, carries 1,859 amendment rows of Natural Resources Canada that depart from the schema. In 1,775 rows amendment_value is blank. In 84 rows contract_date holds the date of the amendment, later than the award date carried by the original contract row of the same contract.
C-2016-2017-Q3-00478, ANSYS CANADA LTD: amendment_value is blank, the amendment added $51,609.24. C-2017-2018-Q2-00127, OLAV CONSULTING CORPORATION: contract_date reads 2017-08-02, the contract was awarded on 2017-07-04.
Why it scores where it does. Reach 3 — national, and every person who uses the dataset. Harm 1 — money and time, no personal injury. Absence of a remedy 3 — no route exists for a member of the public to compel a publisher to correct an open dataset. Persistence 2 — the same departure in 1,859 rows of the same body. Total 9, High, 400 CAD.
