Please refer to CRA website for official answer: http://www.cra-arc.gc.ca/tx/ndvdls/tpcs/ncm-tx/rtrn/cmpltng/ddctns/lns300-350/330/llwbl-eng.html
Since there is no official answer, your best bet is to call the CRA to ask. If the agent says "yes", be sure to make a note of their name and i.d. number.
