Does Microsoft OneDrive and SharePoint store data in Canada?

Yes.
For Canadian customers, Microsoft OneDrive and SharePoint 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.

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.
