Your corporation′s registered office is the address of the corporation in its dealings with government departments and authorities. It is most often the principal place of business of the corporation (e.g. retail store, commercial office, manufacturing plant), but it does not have to be an “office” — it can be any of the places of business for the company. Your registered office may also be your accountant′s office or your lawyer′s office.
Your registered office must be within Canada (if you are incorporating a federal company), or within the province where the company is incorporated. The registered office may be a residential or commercial address, and may not be a post office box.
