# Can I Use My Home Address as My Corporation's Registered Office in Ontario?

> In Ontario, yes: a corporation's registered office (similar to what US filings call a 'registered agent' address, though Ontario requires only a physical location, not a designated agent) can be your home. The Business Corporations Act asks for a genuine physical address inside Ontario; a post office box is not acceptable, but nothing excludes a residential address.

Legal information, not legal advice.

## Verdict: yes, a home address can be your corporation's registered office

**Usually yes.** In Ontario, the Business Corporations Act (RSO 1990, c B.16) defines a corporation's registered office as "the office of a corporation located at the address specified in its articles or in the notice most recently filed" with the province's Central Production and Verification Services Branch. Nothing in that definition, or in the Ontario Ministry's own guidance, requires the address to be commercial rather than residential. A director's or officer's home can be listed as the registered office.

## What the Business Corporations Act actually requires

The Act imposes two conditions that matter here, and neither excludes a home:

1. **The address must be a physical location.** The Ontario government's guide to reading a Corporation Profile Report describes the registered office simply as the "Physical address of the corporation's Head Office/Registered Office," with no carve-out for residential addresses.
2. **The address must be in Ontario at all times.** The registered office "must be located in Ontario at all times." The Act does not require this address to be separate from where a director or officer personally lives.

Put together, these two rules mean a home address qualifies as long as it is an actual physical location inside Ontario, not a mailing convenience.

## Where a home address won't work

The one address type the province rules out explicitly is a post office box. Ontario guidance on business address filings states plainly that "a post office box is not an acceptable address." This standard, applied to the general business address field, reflects the same physical-address requirement that governs the registered office. So:

<div class="table-scroll">

| Address type | Acceptable as registered office in Ontario? |
|---|---|
| Home address physically located in Ontario | Yes |
| Home address located outside Ontario | No, the registered office must be in Ontario |
| Post office box | No |
| Commercial office or third-party address (e.g., a law firm) | Yes, if it is a genuine physical location |

</div>

## Practical considerations before you decide

Choosing a home address as the registered office is legally permitted, but it is a decision with downstream consequences worth thinking through before filing: how mail and legal documents get received at that address, who else may need to access records kept there, and what happens if the household moves.

## What you can do next

Because the registered office is defined by "the notice most recently filed" with the province, the address on record only stays accurate if it's updated whenever the corporation's physical location changes. If a home address stops being usable as the registered office, whether because of a move or a change in circumstances, the corporation's filed notice needs to reflect the new address. Some corporations choose to list a lawyer's, accountant's, or other third party's office as the registered office instead of a home, which is simply a matter of which physical Ontario address is specified in the articles or notice; the Act treats either choice the same way.

## Frequently asked questions

**Does the registered office in Ontario have to be a commercial address?**

No. In Ontario, the Business Corporations Act defines the registered office as the address specified in the corporation's articles or in its most recent notice on file. Nothing in that definition requires the address to be non-residential.

**Can I use a P.O. box as my corporation's registered office in Ontario?**

No. Ontario government guidance is explicit that a post office box is not an acceptable address for corporate registry filings, so the registered office must be a real physical location, whether that location is a home or an office.

**What if I live outside Ontario but incorporate here?**

The registered office must be located in Ontario at all times, regardless of where the directors or officers personally live. A home address only works as the registered office if that home is physically in Ontario.

**Does the registered office need to be separate from a director's personal home?**

No. Ontario's Business Corporations Act does not require the registered office to be distinct from a director's or officer's home; the same physical address can serve both purposes.
