TL;DR

This analysis explains why AI sovereignty cannot be defined solely by a company’s country of incorporation. Legal distinctions, measurement issues, and geopolitical factors complicate the concept, making it more nuanced than simple nationality labels.

European policymakers have declared a new focus on AI sovereignty, but recent developments reveal that defining sovereignty based solely on a company’s nationality is insufficient and misleading. This matters because it affects procurement, regulation, and international data flows, impacting global AI governance.

Recent debates in Europe have centered on whether AI companies are truly ‘sovereign’ based on where they are incorporated. A notable example involves a Canadian AI firm, Cohere, which is considered a ‘European AI champion’ despite being Canadian. The core legal distinction lies in the CLOUD Act, which applies only to US-incorporated providers and their subsidiaries. Canada, not being signed onto a bilateral CLOUD Act agreement, is protected from US data access under that law, unlike US-based companies.

Canada’s legal framework, including Supreme Court rulings such as R. v. Spencer and R. v. Bykovets, explicitly rejects US-style third-party doctrine, making Canadian data protections stronger than those in the US. Despite this, European authorities have shifted their definition of sovereignty, from simply considering where a company is incorporated to whether it is ‘not American,’ a proxy that is increasingly unreliable at the edges—particularly in procurement contexts where measurement and legal standards matter.

Furthermore, Canada holds a European Commission adequacy decision since 2002, allowing data transfers from the EU to Canada under PIPEDA. However, this adequacy is limited to certain sectors and does not cover all data types, especially in provinces with different laws, such as Quebec, which lost its adequacy status in 2014. The scope of this adequacy decision is narrower than many assume, complicating the narrative that Canadian companies are automatically ‘safe’ or ‘sovereign’ in European eyes.

The Wrong Test — Reality Check
AI Dispatch · Reality Check · 16 July 2026

The wrong test: “not American” is not a sovereignty standard

In one press conference, European sovereignty changed definition — from “incorporated in the EU” to “not incorporated in the US” — and nobody asked whether the second is a test or merely a proxy. It’s a proxy. Proxies fail at the edges. The edges are where procurement lives.

✓ First, what’s true — the Canadian case is stronger than critics allow

The CLOUD Act genuinely doesn’t reach Canadian incorporation. Canada has no CLOUD Act executive agreement — negotiating since March 2022, nothing finalized. And the Supreme Court of Canada (R. v. Spencer, R. v. Bykovets) explicitly rejected the US third-party doctrine. On several dimensions Canada is more protective than the US. This is not a hit piece.

The Five Eyes fact, stated precisely

UKUSA (1946): NSA · GCHQ · CSE · ASD · GCSB. CSE’s oversight is real — ministerial authorization, an independent Intelligence Commissioner (a retired judge) who can block, NSIRA review. Now read the operative restriction:

“CSE is prohibited by law from targeting the private information of Canadians, or any person in Canada.”

The protection is national and territorial. Europeans are neither.

Not an accusation — architecture. It’s structurally why Safe Harbor fell: protections protect the home nationals.

The adequacy gap nobody mentions

Canada has adequacy since 2001/2002 (Decision 2002/2/EC). But its scope is PIPEDA-only — employee data largely excluded; Alberta/BC/Quebec regimes never got adequacy; Quebec’s was withdrawn in 2014.

It was assessed against PIPEDA’s commercial framework — not against Canada’s intelligence laws or Five Eyes participation.

That’s the same hole the CJEU punched through Safe Harbor. In fairness: the Commission did examine public-authority access and found redress “accessible to non-Canadian nationals.” That clause is the best argument Canada has — and NSIRA is largely classified. Unsettled, not resolved.

⚠ The nexus problem — incorporation is not the test

US courts have been clear for 40 years: Bank of Nova Scotia — American courts enforce subpoenas against entities subject to US jurisdiction even where compliance violates foreign law, and fine for refusal. Jurisdiction attaches to presence and activity, not the incorporation certificate. So corporate pledges to “resist” are sincere and legally insufficient. And Canadian exposure creeps through ordinary commercial expansion:

BCE bought Ziply Fiber (US) Aug ’25 TELUS — 1,600+ US staff Shopify — 57% of txns in US; NY principal executive office None changed nationality. All changed nexus. So: what US nexus does Cohere have? Customers · ops · Microsoft partnership · US investors · a likely US listing. Nobody has asked.
The honest hierarchy — three standards, ranked by what they actually protect
✕ A proxy
“Not American”
Fails on nexus, fails on Five Eyes statutory architecture, fails when the ally’s interests diverge — and fails silently, because nobody’s measuring. This is what Europe just adopted.
◐ A test
“EU-incorporated”
SecNumCloud’s 24%/39% cap — narrow, arithmetic, checkable from a shareholder register. Also undeniably protectionist. Both true. What Europe already had — and just stepped back from.
✓ An architecture
Open weights · your keys · air-gappable
Requires trusting no jurisdiction, no ally, no election result, no executive directive. The only posture that survives every question below.
Europe just moved from the second to the first — and called it progress.
✓ The right test — enforceable, auditable control
1Who can compel you, under what standard, with what judicial review?
2Is there redress for a non-national? (US–UK/AU deals create none)
3What’s your nexus — not your incorporation?
4Who holds the keys, and can they be compelled to produce them?
5Can you leave, and how fast? (12–18 months of exit work)
6Can it be air-gapped?
Notice what happens down the list: the questions stop being about jurisdiction and start being about architecture. That’s not an accident — that’s the finding.
The take

The Five Eyes question isn’t “is Canada spying for America” — that’s the tabloid version, it’s unsupported, and it’s a distraction. The real question is duller and more damaging: why is Europe using nationality as a substitute for measurement? Because a proxy is cheap and a test is expensive. “Not American” lets you approve the deal, satisfy the minister, and skip the register, the nexus, the redress. It produces a press release. It does not produce protection. Every sovereignty claim here is a jurisdictional bet — that a legal system, an alliance and a political mood hold for the life of your data. The Canadian bet is genuinely better than the American one. It’s still a bet. The only positions that don’t require one are where you hold the weights and can pull the plug. If the answer is “well, they’re not American” — you haven’t been given a standard. You’ve been given a mood.

Implications of Proxy-Based Sovereignty Definitions

This shift in defining AI sovereignty based on proxies like nationality rather than legal, technical, or measurement standards can lead to misjudgments in procurement, regulation, and international data sharing. It risks oversimplifying complex legal protections and undermining nuanced governance, potentially affecting trust, compliance, and the actual sovereignty of AI systems.

Legal and Geopolitical Foundations of Data Sovereignty

The concept of sovereignty in AI is intertwined with legal frameworks like the CLOUD Act, which governs US data access, and Canada’s foreign intelligence laws, which explicitly protect data of Canadians and residents. Canada’s status as a Five Eyes partner and its legal protections contrast with the EU’s approach, which emphasizes data protection and redress mechanisms. These differences highlight that sovereignty cannot be reduced merely to geographic labels, but must involve measurement of legal protections, oversight, and jurisdictional boundaries.

Key Questions

Why is nationality alone not enough to determine AI sovereignty?

Because legal protections, oversight, and jurisdictional boundaries define sovereignty more accurately than mere incorporation location. Proxies like nationality can be misleading, especially at the edges of procurement and regulation.

How does Canadian law protect data compared to US law?

Canadian law explicitly protects data of Canadians and residents, with Supreme Court rulings rejecting US-style third-party doctrine. Canada’s legal protections are stronger and more territorially bound than those in the US.

What role do international agreements play in AI sovereignty?

Agreements like the EU-Canada adequacy decision facilitate data transfers but are limited in scope. Ongoing negotiations, such as Canada-US CLOUD Act agreements, influence how sovereignty is practically enforced across borders.

Will measurement standards replace proxies in defining sovereignty?

It is uncertain. While measurement-based standards are increasingly discussed, their adoption depends on legal, technical, and political developments that are still unfolding.

What are the risks of oversimplifying sovereignty based on nationality?

It can lead to misjudgments in procurement, regulation, and international data sharing, potentially undermining actual control and protections over AI systems.
