Every federal corporation in Canada receives a seven‑digit corporation number under the Canada Business Corporations Act (CBCA). The number anchors the Corporations Canada record and appears on each filing the register publishes.
That federal register is only one layer of the system. Provinces run their own corporate registers, and many operating companies incorporate provincially rather than under the CBCA. Federal entities still surface often in diligence work. Foreign parents tend to use them as holding vehicles when arranging Canadian assets or issuing debt.
Corporations Canada keeps a fairly orderly dataset. The register publishes the legal entity record, the current officers and directors, plus the filing history attached to the corporation number. What it does not publish is a beneficial ownership register comparable to the UK PSC dataset or similar registers used in parts of the EU.
Fields that actually appear in the registry
A company profile from the federal register follows a stable shape. Query it through OpenRegistry and those attributes appear in the unified schema as well as the raw jurisdiction_data returned by Corporations Canada.
Common examples:
corporationNumber– the seven‑digit CBCA identifier
businessNumber– the CRA business number when present
status– usually "Active" or "Dissolved"
dateOfIncorporation
registeredOfficeAddress
Director records are public too. The register stores entries with fields such as:
firstName
lastName
residentialAddress
appointedDate
Addresses carry some historical weight. The CBCA once required at least 25 percent of directors to be resident Canadians. Parliament removed that rule in 2021. Older records still show the residency indicator. It can help reconstruct board composition at the moment a financing closed or an acquisition went through.
Filings add another signal. Corporations Canada records events like annual returns, articles of amendment, continuances from provincial statutes, and dissolution notices. Each entry includes a filing type along with the date tied to the corporation number.
What you will not get from the federal registry
Beneficial ownership is the obvious gap. Canada does not run a public federal beneficial owner register comparable to the UK PSC regime created by the Small Business, Enterprise and Employment Act 2015.
Expectations shifted after the Corporate Transparency Act appeared in the United States. Many compliance teams now assume the same dataset exists elsewhere. Corporations Canada does not publish it. The federal government has discussed building a national beneficial ownership register, though most of that information still sits inside private corporate records or law‑enforcement systems as of 2026.
Shareholder registers are absent as well. The CBCA requires corporations to maintain them internally. Certain parties may request access under the statute. The information does not appear in the public search interface.
That absence affects AML and sanctions work. The federal register confirms the legal entity. It shows directors and structural changes through filings. It does not reveal the ultimate owners.
Querying Corporations Canada through OpenRegistry
OpenRegistry exposes the federal register through MCP tools that AI assistants can call directly. Each request reaches the government source rather than a cached dataset.
Most searches start with a company name or the corporation number.
Example tool call:
search_companies({
"jurisdiction": "CA",
"query": "Shopify"
})
The response lists matching corporations together with their corporation numbers and current status. Once you have the identifier, pulling the full company profile becomes straightforward.
get_company_profile({
"jurisdiction": "CA",
"company_number": "426160-7"
})
Governance details sit behind another call.
get_officers({
"jurisdiction": "CA",
"company_number": "426160-7"
})
Filings fill in the timeline.
list_filings({
"jurisdiction": "CA",
"company_number": "426160-7"
})
Each filing entry reports the document type and filing date. Some also include a document link when the upstream register publishes one.
A structural quirk in Canadian diligence
The federal register rarely tells the whole story. Many operating companies incorporate in Ontario, British Columbia, or Québec instead of under the CBCA. A holding company may sit at the federal level while the real operating entities appear only in provincial registers.
This split causes a familiar mistake during diligence. Analysts confirm the federal parent and assume the corporate chain ends there. Often it does not. Operating subsidiaries may exist only in provincial databases.
Cross‑border M&A structures show the pattern often. A US parent forms a CBCA holding company. That entity owns a British Columbia operating company where the contracts and staff sit. Search the federal register alone and the structure looks thinner than it really is.
Reproducibility matters during audits and regulatory reviews. A regulator should be able to repeat the search and retrieve the same corporation number, director record, and filing dates. Direct queries against the register of record help with that. Cached aggregator datasets drift if they refresh only from time to time.
