Data Residency & Sovereignty Preview Outline
Framework for keeping sensitive AI & data assets resident in Canada while enabling performance, portability and multi‑region resilience.
1. Data Classification Tiers
- Tier 0: Public open datasets
- Tier 1: Internal non-sensitive
- Tier 2: Controlled (PII hashed/obfuscated)
- Tier 3: Restricted (regulated / financial)
- Tier 4: Critical (crown assets / national security)
2. Control Plane Anchoring
- Primary orchestration inside Canadian trust boundary
- Out-of-band break-glass path with hardware key
- Region failover via signed policy bundles
3. Encryption & Key Domains
- Segregated KMS per tier
- Hardware backed keys (HSM) for Tier 3/4
- Dual-person approval for sensitive key ops
4. Lawful Access Minimization
- Data minimization + tokenization strategy
- Redaction pipeline pre export
- Compartmentalized logging with retention policy
5. Exit & Portability
- Data egress bundles: manifest + hash ledger
- Time-boxed wipe attestations
- Format neutrality for model artifacts
Full version will include control plane diagrams, policy templates and bilingual annex. Feedback welcome.
