DSAR Deep‑Dive

A practical, evidence‑focused walkthrough of how Canadian SaaS teams can prepare DSAR workflows for PPCDA’s proposed direction.

A Data Subject Access Request (DSAR) is a user request to access, delete, or correct their data. PPCDA is a tabled federal privacy bill that reinforces the need for verifiable evidence at every step. DSARs are often the earliest and most operationally painful workflow — and the fastest way to expose gaps in data mapping, retention, and vendor management.

The DSAR Workflow at a Glance

1. Intake & Verification

Capture the request, verify identity, timestamp the intake, and classify the DSAR type.

2. Data Location Mapping

Identify all systems containing user data — internal, vendor, archived, and legacy.

3. Evidence Collection

Gather exports, logs, screenshots, deletion proof, and vendor confirmations.

4. Fulfillment

Provide the user with their data, deletion confirmation, or access report.

5. Audit Trail

Record every step — timestamps, actions, systems touched, and evidence collected.

6. Closure & Review

Close the request, store evidence, and identify workflow gaps for future improvement.

Detailed DSAR Breakdown

1. Intake & Verification

  • Timestamped DSAR intake log
  • Identity verification steps (email, MFA, ID match)
  • Classification of DSAR type (access, deletion, correction)
  • Requester communication log

2. Data Location Mapping

  • List of all systems containing user data
  • Vendor systems included in the mapping
  • Legacy or archived systems identified
  • Evidence of data ownership across teams

3. Evidence Collection

  • Deletion logs or confirmation artifacts
  • Vendor confirmations for data removal
  • Access logs showing who touched the data

4. Fulfillment

  • Clear, complete response to the user
  • Deletion confirmation (if applicable)
  • Access report (if applicable)
  • Timestamped delivery log

5. Audit Trail

  • Full timeline of DSAR handling
  • Evidence of each step taken
  • Team ownership mapping
  • Retention of DSAR evidence for audit readiness and PPCDA‑aligned workflows

6. Closure & Review

  • DSAR closure log
  • Evidence stored centrally
  • Workflow gaps identified
  • Improvements documented

Prepare for PPCDA’s Evidence Expectations

PPCDA is a tabled federal privacy bill. Teams preparing early can strengthen evidence workflows, reduce audit friction, and align operations with the direction regulators are already moving.
