Does Microsoft 365 store data in Canada?
Word, Excel, PowerPoint, Outlook, Teams, OneDrive, SharePoint
Yes.
For Canadian customers, Microsoft 365 stores data in Canada. It is owned by a US company, so the US CLOUD Act can require it to produce data it controls, wherever that data is stored.
Tier 4: US-owned, Canadian regionData can be stored in Canada, and the owner is a US company.

The facts, claim by claim
- Where data is stored
- Canada, for tenants provisioned in Canada: Exchange mailbox content, SharePoint and OneDrive files, and Teams chat messages stored at rest only in the Canada geography (Microsoft Product Terms)
- Where it is processed
- Not covered by the at-rest commitment
- Support and backups
- Not stated on the pages read
- Owner
- Microsoft Corporation (Redmond, WA) · Parent country: United States
- Servers run by
- Microsoft data centres in Canada · US company
- Customer-held keys
- Not recorded
- Certifications
- CCCS Medium (Microsoft 365 is in Microsoft's assessed scope)
- Worth knowing
- The default for most Canadian public bodies. Data at rest stays in Canada by contract; the owner is a US company.
What the rules say about this
- US CLOUD Act: The owner is a US company: storing data in Canada does not take it out of reach of US legal process.
- Nova Scotia public bodies: Storage and access must both be in Canada: check support access and backups, not only storage.
- Québec Law 25: Canada is not Québec: storage in Toronto still needs a privacy impact assessment for Québec data.
- OCAP®: Data held by any outside vendor is not in the Nation's possession, whoever owns the vendor.
