You are not entitled to claim the Family tax cut.  One of the conditions is that you or your spouse or common-law partner must have ordinarily lived with your child who is under 18 at the end of the year.  For more info please see http://www.cra-arc.gc.ca/tx/ndvdls/tpcs/ncm-tx/rtrn/cmpltng/ddctns/lns409-485/423-eng.html
