Add language-specific company branding to your directory

We are onboarding our regional office in Montreal to Office 365.  I have been playing with custom branding for the French speakers but am unsure if the new sign-in screen will display to them.  The only language option in  Users and groups > Company branding > New language  is French (France).  Will the custom logos and text apear to my users in French Canada?  https://docs.microsoft.com/en-us/azure/active-directory/customize-branding#add-language-specific-company-branding-to-your-directory.

Thanks in advance for any advice.
