Nope! You can create an account and link existing applications including EE to the new account. An account is a way for you to manage your applications and it is not an application itself. For example, in my previous account, it shows my Study Permit application, visa application, Post Grad Work Permit application, and EE application. I created a new account and chose to link only my EE application to my new account. When I received the ITA, there is a new application created, which is PR application.
