If a firearm is restricted, it means the individual must obtain the higher-level firearms licence, the restricted possession and acquisition licence, or RPAL as you indicated. It also means that the firearm itself would need to be registered with the Canadian firearms program firearms registry.
Also, if you wished to use that firearm for any lawful purpose, you would require an authorization to transport in most cases for that purpose. There are some exceptions. There are automatic authorizations to transport for regular uses like going to the range, but broadly speaking you have to have an authorization to move a restricted firearm from your home to use it.
