You want to add a business name under your named corporation. An example would be ABC Widgets Canada Inc. carrying on business as ABC Holdings. This option does not provide a corporate named company but a business name under your named corporation.
A tradename is the name a business uses to identify itself. A trade name can be different from the legal name (incorporated name) of a business. For example, a business might be incorporated as 'ABC Holdings Inc.' and do business under the tradename 'DEF Consulting'.
Alternatively, if signage or promotion of the business name is required, it may be beneficial to register the same business name without the legal ending or full incorporated business name. For example, a business might be incorporated as 'ABC Holdings Inc.' and do business under the tradename as 'ABC Holdings' or 'ABC'
