The domicile you declared when your business was registered is public information. Anyone can look it up at the register, including an unhappy client, a former partner, or a stranger with a search bar. By the end of this article you will know why a post-office box does not solve anything and what the only compliant way is to take your home address out of circulation.
What the register actually shows
When a business registers in Quebec, it must declare a domicile for each director and, depending on the structure, for the business itself. That domicile sits in the public file. It is not masked, not anonymized, not reserved for internal use: anyone browsing the directory of corporations by city or ordering an extract from the Registraire can see it, with no need to justify the request or identify themselves to the business in question.
For an incorporated freelancer working from home, or for a director who simply listed a home address out of convenience at incorporation, the outcome is the same: the address where their kids sleep is one click away from anyone. This is not a flaw in the system. It is the system working exactly as designed, which is precisely why the fix has to be the declared address itself, not the hope that nobody ever looks.
Why a post-office box does not work
The natural reaction is to swap a home address for a post-office box. The Registraire refuses a post-office box as a domicile; a professional address is the only compliant alternative. A post-office box is not a place where someone can be physically reached, and that is exactly what the register requires: a real location where legal service can be received by a person actually present.
In other words, this is not a checkbox you route around with a mail subscription. It is a substantive requirement, which is why some owners leave a home address sitting in the file for years, simply because they never found the alternative, or after trying the post-office-box route and hitting a refusal at filing time.
A professional address, the only way out
A real professional address — an office, a shared workspace, or a dedicated service that receives mail and legal service on the business’s behalf — meets the requirement. It replaces the personal domicile in the declaration filed with the register, without changing how the business actually operates: you keep working from wherever you want, only the declared address changes.
The change is made through an update to the file at the register, the same way as any other change of address or director. It is not a separate or exceptional process: it is a declaration like any other, following the same rules described on our how it works page. Once the declaration is filed and processed, the old address stops appearing on new extracts of the file.
What it costs to not do it
Leaving a home address on file costs nothing in dollars. The cost sits elsewhere: in the permanent visibility of where you live, reachable by anyone who types your business name into a search engine or browses the register out of curiosity. It is a personal-security problem, not just an image one, and it does not get solved by hoping the file stays unnoticed.
| Situation | What is visible | What to do |
|---|---|---|
| Home address declared | Residential address, public | Replace with a professional address |
| Post-office box declared | Refused by the Registraire | Not compliant, needs correction |
| Professional address declared | Business address, public | Compliant, no action needed |
What MonNEQ does about it, for 39 $ a month
MonNEQ offers a professional address for 39 $ a month, which replaces the personal domicile in the declaration filed with the register and receives official mail on your behalf. Every filing MonNEQ prepares is checked by a person before it is sent to the Registraire, including this address change: nobody hits send until a human has read the file. The update fits inside the same ongoing handling as the rest of your annual obligations, described on the pricing page. If you want to see what your file currently shows first, the free file check reveals the address that is publicly listed today before you decide anything, and the security and government access page explains how those accesses are managed.
