SOC 2 vs ISO 27001 in Canada (2026): Which Do Your Customers Want?

Canadian companies selling software or services increasingly get asked for a security attestation — but which one? In 2026 the honest answer depends on where your customers are. US buyers almost always ask for SOC 2; international and EU buyers ask for ISO 27001; and Quebec's Law 25 and the incoming federal Bill C-26 add Canadian obligations on top. Here is how to choose.

SOC 2 vs ISO 27001: what each one is

SOC 2 is an attestation report, issued only by a licensed CPA firm, describing how your controls meet the AICPA Trust Services Criteria over a point in time (Type 1) or a period (Type 2). ISO 27001 is an internationally recognised certification of a management system (the ISMS), issued by an accredited certification body. One is a report your customers read; the other is a certificate you display.

What about Quebec Law 25 and Bill C-26?

Neither SOC 2 nor ISO 27001 is a substitute for Canadian law. Quebec's Law 25 imposes some of the strictest private-sector privacy obligations in North America, and the federal Bill C-26 (CCSPA) is advancing with significant penalties for critical-infrastructure operators. A well-built ISMS makes meeting these far easier, but you should map to them explicitly.

How to choose

• Selling mostly to US customers: start with SOC 2 (Type 2 if you can).
• Selling internationally or into the EU/UK: start with ISO 27001.
• Both markets: build one ISMS and map it to both — the control overlap is large.
• Operating in Quebec or in critical infrastructure: layer Law 25 / Bill C-26 mapping on top.

Frequently asked questions

Do Canadian companies need SOC 2 or ISO 27001?

It depends on your buyers. US customers typically request SOC 2; international and EU customers typically request ISO 27001. Many Canadian firms eventually pursue both because the underlying controls overlap heavily.

Does SOC 2 or ISO 27001 satisfy Quebec Law 25?

No. Both strengthen your security posture and make compliance easier, but Law 25 has specific Quebec privacy obligations that must be addressed directly.

Can one project deliver both SOC 2 and ISO 27001?

Largely yes. A single ISMS build can support both, with the SOC 2 report issued by a CPA firm and the ISO 27001 certificate by an accredited body.
