Does T1 return contain T1013 information?
T1013 is submitted separately from T1 return, even when you have T1013 form in return file, it won't file to CRA if you only do efile/netfile.
To file T1013, you need to choose menu "Start | Submit T1013 Electronically". Filing T1013 only contains T1013 information, no T1 return amounts are transferred to CRA.
