When you register a business name or incorporate in Ontario, your address becomes part of the public record on the Ontario Business Registry. To keep your home address private, list a professional business address instead. It meets the legal requirement of a real Ontario street address while keeping your home off the public listing.

Your address goes public the moment you register

Many first-time founders do not realize this until it is too late. The instant you register a business name or incorporate in Ontario, the registered or head office address you provide, along with your business and mailing addresses, becomes searchable on the public record.

  • For Ontario registrations, that record is the Ontario Business Registry.
  • For federal corporations, the details also appear on Corporations Canada.
  • Even a sole proprietorship that registers a business name lists a business address publicly.

If you use your 家庭住址 (your home address) to satisfy that requirement, it is visible to anyone who searches: customers, suppliers, marketers, data brokers, and complete strangers. Once it is out there, you cannot easily pull it back.

Why a public home address is a real problem

Putting your home on the 公开记录 (public record) is not just a theoretical concern. It has practical consequences for home-based founders.

  • Anyone can find where you live. A curious customer, a disgruntled buyer, or a stranger can look up your registration and get your front door.
  • Marketers and data sites harvest it. Your home address gets copied into third-party databases and mailing lists that are hard to clean up.
  • Unwanted mail and visitors arrive at home. Returns, walk-ins, sales flyers, and unsolicited couriers can all show up where your family lives.
  • It looks less professional. A residential address on your filings and website signals a hobby rather than an established business.

For anyone running a business from home, protecting your 隐私 (privacy) is reason enough to keep your home address off every public filing.

The fix: a professional business address

The requirement Ontario cares about is simple. Your 注册办公地址 (registered office address) must be a real physical street address where legal and government documents can be delivered. It does not have to be your home.

A 虚拟办公室 (virtual office) is a genuine office street address that you are entitled to use as your business address. Because it is a real, staffed location, it satisfies the legal requirement while your home address never appears.

  • A 邮政信箱 (P.O. box) is NOT acceptable for a registered or head office, because documents must be deliverable to a real physical location.
  • A mail-only service on its own is not an office address either.
  • A real virtual office is a Class-A street address, so it does qualify as your registered or head office.

The result is the best of both worlds: your business is fully registered and reachable for legal purposes, but the address on the public record is a professional office rather than your living room.

One address for your whole business

A professional business address is not just for the registration filing. The same address can anchor your entire business identity:

  • Your registered/head office on the incorporation or business-name record.
  • Your CRA Business Number.
  • Your HST and payroll accounts.
  • Your website and business cards.
  • A business bank account.

Using one consistent, credible address across all of these keeps your presentation professional and, more importantly, keeps your home address out of every one of them.

A note on directors and address for service

It is worth being precise here, because this is general information and not legal advice. When you incorporate, individual directors’ addresses may still be recorded as part of the filing. That is separate from the registered office address.

In many cases, however, an address for service can be the business address rather than a personal home address. The practical takeaway: using a professional business address for the registered office is a strong first step, and you should confirm the specific address-for-service options for your situation before you file. You can review the official requirements on the Ontario Business Registry.

A simple checklist before you file

Run through this before you submit your registration or incorporation:

  • Confirm the address is a real street location. A P.O. box will be rejected for a registered office.
  • Make sure legal documents can be received there. This is the core requirement.
  • Use the same address everywhere for CRA, HST, payroll, banking, your website, and cards.
  • Check the director and address-for-service fields so you are not quietly listing your home.
  • Keep your home address off every public field you can.

Getting this right at registration is far easier than trying to scrub your home address from public records later.
