Changing a corporation name is one of the most common updates business owners make as their company evolves, expands, or rebrands. Whether you're looking to change corporation name in Canada, update your Ontario corporation name, or align your branding with a new direction, the process must be done correctly to stay compliant.
Many business owners assume it’s just a simple update, but in reality, changing a corporate name involves government filings, name searches, and approvals that vary depending on whether your business is federally or provincially incorporated.
In this guide, we break everything down step-by-step so you can confidently change your business name without delays, penalties, or confusion.
What Does It Mean to Change a Corporation Name?
Changing a corporation name means legally updating your registered business name with the government while maintaining the same corporate entity.
Your corporation:
Remains the same legal entity
Keeps the same CRA business number
Keeps existing contracts and obligations
Only the legal name changes
When You Can Change Your Corporation Name
You can change your corporation name if:
You are rebranding
Expanding services/products
Merging or repositioning your business
Fixing a naming issue or conflict
Aligning with marketing strategy
You cannot use a new name that:
Is already taken or too similar to another corporation
Is misleading or restricted under naming rules

Be distinctive
Not be confusingly similar
Include a legal element (Inc., Ltd., Corp.)
Example:

Step 2: Conduct a Name Search (NUANS Report)

It checks:
Existing corporate names
