How to search
Start with company search and jurisdictionCode: "ca-on". Pass the name as companyName, a registration number as companyNumber, or both to narrow the result. Here companyNumber is read as registrationNumber.
Fields
To say exactly what you mean, send an advancedQuery instead. Ontario (CA) understands these fields:
| Field | What it does |
|---|---|
name | Entity name to search for. |
registrationNumber | Ontario Corporation Number (OCN) or Business Identification Number (BIN). Not the federal CRA Business Number. |
Examples
{ "jurisdictionCode": "ca-on", "advancedQuery": { "name": "MAPLE LEAF SPORTS" }}Ontario (CA) also accepts registrationNumber.
Company identifiers
Search by passing the registration number as companyNumber — it is matched against the schemes this register can search on, so you do not name the scheme yourself. Not every scheme below is searchable; the rest label the values returned in a company’s identifiers.
| Identifier | Appears as | Format |
|---|---|---|
| Ontario Registry ID | ca_ontario_registry_id | No fixed format |
Documents you can order
| Document | Order by | Status |
|---|---|---|
| CA-ON Ontario Business Registry Document A copy of one filing recorded by the Ontario Business Registry since its launch on 2021-10-19 — an annual return, articles, a notice of change — as the registry's own PDF. Identified by the kausateDocumentId the document list returns; filings archived before the launch are listed but not orderable. Ordered from ServiceOntario and usually delivered within a minute. | A document ID from the list operation | Live |
| CA-ON Ontario Business Registry Profile Report The Ontario Business Registry's Profile Report, certified a true copy of the record by the registrar: the entity's current registered or head office address with street and postal code, active directors with their address for service, resident-Canadian flag and start date, active officers, and the name history. Ordered by this document's code for a corporation or partnership, with no document list needed first; the kausateDocumentId a document list returns for it works too. Ordered from ServiceOntario and delivered as the registry's own PDF, usually within a minute. | CAONPR | Live |
Those shown with a code have no cross-jurisdiction shortcut: order them by the code itself — for example CAONPR. The rest are filings whose availability differs per company: call list documents first and order the ID it returns.
