Box 12 - Social insurance number (SIN) or individual tax number (ITN)

Enter the Canadian social insurance number (SIN) assigned to the non-resident individual. If a SIN has not been assigned, ask the non-resident if they have been assigned an individual tax number (ITN) or a temporary tax number (TTN) by the CRA and enter it here. An ITN is normally assigned to a non-resident individual if they have applied for a waiver or a reduction of withholding or if they have previously filed a Canadian tax return. If a SIN, ITN, or TTN has not been assigned to the non-resident, leave the box blank.
