Note on Exemptions Applied

1. Section 19(1) — Personal Information The complainant's name, home address, telephone number, and Social Insurance Number are personal information about an identifiable individual within the meaning of the Privacy Act definition incorporated by reference in s. 19(1) of the Access to Information Act. There is no indication in the record that any of the exceptions in s. 19(2) apply (e.g., consent, public availability, or that disclosure is otherwise permitted), so this information has been withheld in full. The name has been redacted throughout, including subsequent references ("Ms. Olsen"), as its release in combination with the surrounding details would still identify her.

2. Section 20(1)(b) — Third-Party Confidential Financial/Commercial Information The specific unit pricing ($184.50 per unit for the first 2,000 units) was explicitly identified as having been supplied to the institution "in confidence" by Northgate Systems Ltd. This meets the test under s. 20(1)(b) for confidential commercial/financial information supplied by a third party and consistently treated as confidential by that party. It has therefore been withheld.

Information Released

  • The general nature of the complaint (delayed payment, mismatch of address, 47-day delay) — operational, not personal to a degree requiring withholding beyond the identifiers above.
  • The file number (CS-2025-0192).
  • The name of the third-party vendor (Northgate Systems Ltd.) and the general subject matter of its proposal (address-verification module) — the identity of the vendor and the general nature of the module are not, on their face, confidential and their disclosure does not reveal the withheld pricing.
  • The planned deployment timeframe (April 2025).
  • All sender/recipient/date/subject line information, as this relates to a government official acting in an official capacity and is not personal information for the purposes of s. 19(1).

No missing instructions or conflicts were identified in the record that would require clarification before release under this analysis.
