Register a business in Ontario
How do I find the route to register a business in Ontario?
Ontario's registration guide helps you move from a chosen business structure to the correct registry transaction. It lists registration routes for several entity types and explains the account setup involved. Check the requirements for your particular structure before submitting. Ontario's business identification number is distinct from a federal CRA business number, so do not treat them as substitutes.
Where to begin
- Confirm the appropriate business structure and registration requirements.
- Check the proposed name and select the correct entity registration route.
- Follow Ontario's official setup instructions and retain the registration record.
Before you open the official service
- The intended ownership structure
- The proposed business name
- A working business contact email
Keep your actual documents and account details off this website. Use the official service’s current checklist before applying.
What to check for your situation
This guide does not recommend a legal structure or establish registration obligations for your circumstances. Confirm current requirements and fees on the official page.
Fees, processing times and document rules can change. This page helps you navigate; it does not confirm eligibility or replace the government’s instructions.
