Where does it say new applicants only? Those were Badenoch's words. It is not what I am reading in the link provided.
It appears to apply for everyone. An application (renewal) is new each and every time. Semantics.

Expanded background checks
The legislation requires expanded background checks over the lifetime of an applicant seeking to acquire a firearms licence rather than just the five years immediately preceding the application. It will also add criteria that must be considered in deciding whether to grant a firearms licence, including a history of harassment, whether the applicant was ever subject to a restraining order, and whether the applicant poses a risk of harm to any person.
