Why is it important to file changes?

Business records should be kept up-to-date and accurate for many reasons.

Legal Service – Should any legal action be filed against a business, it’s essential that a current address is on file, for proper delivery of any legal documents. If legal action is taken against your company, but the address or contact information is not accurate and current, judgment may be made against you without your knowledge. Business owner(s) have the responsibility to file changes and keep their records up-to-date promptly after any change happens.

CRA—Revenue Canada may be required to contact the business owner(s) regarding any issues with the business.

Banking – Where there are multiple owners involved, banks must know if any owners have been removed or added to the business, as well as their updated contact information, so the bank can remove or add authority to owners over any bank accounts.
