Footnotes capture three details that matter most for a Canadian buyer: jurisdiction, whether the terms can change on notice, and who owns the audit log.
ChatGPT Enterprise / Team
OpenAI retains conversation logs for up to 30 days for abuse monitoring — accessible to OpenAI staff and to US legal process. Zero data retention is available only by separate written agreement, and only on certain models. This is not your default. United States company — CLOUD Act applies.
Microsoft 365 Copilot
Uses your Microsoft Graph as context — it reads your SharePoint, Exchange, OneDrive, and Teams. Retention follows the M365 commitments, not Canadian commitments. United States company — CLOUD Act applies.
Azure OpenAI
The Canadian region addresses the physics of the data, not the jurisdiction. Microsoft Corp. remains subject to the CLOUD Act. See the trust-hub section on Azure for details.
Google Gemini for Workspace
Content is not used for advertising, but it is processed by Google's global infrastructure under the control of the US parent. United States company — CLOUD Act applies.
Mistral Cloud
Out of CLOUD Act reach. However, any transfer from Canada is still cross-border (GDPR ≠ Bill 25). A PIA is required. The posture is better than US vendors, but still weaker than an on-site tonia.
Cohere
Out of CLOUD Act reach for workloads processed on Canadian infrastructure. This is the closest cloud posture to tonia. But: not on-premises, no on-site tonia audit log you control.
