If there are not additional taxes even after adding back the interest, then there may be no action.
All re-assessments due to unreported T4, T5 etc. are computer generated. CRA automatically match T4, T5 etc. you filed with the information they have on their system.
I have seen CRA re-assessed people with unreported interest from Australia and HK.

Only if you have to file RC243 because you have tax liabilities, then there is a deadline to file or face penalties.
