What the rules say about this
- Nova Scotia public bodies: Storage outside Canada needs the head of the public body's approval and a report.
- Federal Protected B: Canadian facilities are the principal option departments must evaluate; this listing offers none.
- Québec Law 25: A privacy impact assessment is required before personal information leaves Québec.
- OCAP®: Data held by any outside vendor is not in the Nation's possession, whoever owns the vendor.
