Frequently asked questions about the Canada KYB API
What company data can I verify in Canada?
For a Canada company, the API returns the company record read live from the official company registry: the entity name, type, status, registration number, address, and registration date, along with the available registry documents. See the table above for the full Canada availability.
Does the API return beneficial ownership (UBO) data for Canada companies?
For Canada, the official company registry does not publish shareholder or beneficial-owner data, so the API returns the company record and the controlling parties and officers rather than a shareholder or beneficial-owner list. Where you need ownership for an entity in a jurisdiction that does publish it, the recursive org-chart (GET /v2/Companies/{caseCommonId}/org-chart) resolves it. See the UBO API.
Can I retrieve official registry documents for Canada companies?
The API returns the registry documents the register makes available for Canada, pulled at verification time, via the documents endpoint (GET /v2/Companies/{caseCommonId}/documents).
Is there a free sandbox for testing Canada company verification?
Yes. The Know Your Customer sandbox at https://api.knowyourcustomer.dev is a free, high-fidelity test environment. Request free sandbox access to start testing.
