How can I submit my T4a information after I have submitted the eFile to CRA?

[kevinwong2008]

I have submitted my eFile a week ago, only to find that I have left out the information on  a T4a.  How and when should I submit the additional information?

Wait until you receive your Notice of Assessment and then request an adjustment to your return. For more info, please see http://www.cra-arc.gc.ca/tx/ndvdls/tpcs/ncm-tx/chngrtrn-eng.html
