The Canada Business Registry sounds like one thing, but it's really a cluster of systems — one federal search tool and thirteen provincial registries that feed into it. Knowing what it actually does saves you from registering in the wrong place. Here is what the Canada Business Registry is, what you can do with it, and when you need it.
What Is the Canada Business Registry?
The Canada Business Registry is the federal portal where you can search every Canadian-incorporated business. It pulls from Corporations Canada plus all provincial and territorial registries, giving you one search tool to look up any incorporated business in the country by name, BN, or corporation number.
What You Can Search For
The registry lets you confirm whether a business is active, check its legal structure, and see where it's registered. Common uses:
- Confirm a supplier or contractor is a real registered business
- Check name availability before registering your own
- Find directors and basic corporate details (for federal corps)
- Verify the BN matches what's on an invoice
How to Register Your Business With It
You don't register directly with the Canada Business Registry — you register with either Corporations Canada (federal) or the province you operate in. Once registered, your business automatically appears in the federal search.
For most Ontario-based small businesses, registration happens through the Ontario Business Registry. For businesses operating in multiple provinces, federal incorporation through Corporations Canada is often the better call.
Keeping Your Registry Record Current
If you're incorporated, you have to file an annual return — federally or provincially — to stay on the registry as "active." Let this lapse and you risk administrative dissolution, which means your corporation stops legally existing. Sole proprietorships have simpler renewals (Ontario is every five years).
Practical Tips
Before you sign any contract with a new vendor or agency, look them up. It takes ten seconds and catches a surprising number of shell operations. If you run your own client operations, a clean CRM like Threecus lets you store BN and registration details alongside each client so you have it for invoicing and tax reporting.
