You should send a copy of your T4 when paper filing your return. However you are not required to submit any of your home purchase documents at this time. They should be kept in a safe place in case you are requested to submit them to CRA at a later date. Please see http://www.cra-arc.gc.ca/tx/ndvdls/tpcs/ncm-tx/rtrn/cmpltng/ddctns/lns360-390/369/clm-eng.html
