This process is commonly used when launching a new brand, adding a second business name, or separating different lines of work. In Ontario, a Sole Proprietor (business owner) can hold more than one registered business name, each with its own registration. This guide explains when you need a new registration, what information is required, and how to register a new business name correctly\u2014while avoiding common mistakes that cause delays or confusion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Do I Register a New Business Name For My Sole Proprietorship?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To register a new business name for your <a href=\"https:\/\/www.ontariobusinesscentral.ca\/forms\/sole-proprietorship-registration.php\">Sole Proprietorship in Ontario<\/a>, you must complete a <strong>new Business Name Registration<\/strong>. Business names cannot be changed or edited once registered\u2014each new name requires its own registration.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This applies whether:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You are adding a second business name<\/li>\n\n\n\n<li>You want to operate under a new brand<\/li>\n\n\n\n<li>Your current business name no longer fits your services<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Can a Sole Proprietorship Have More Than One Business Name?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Yes.
