The guide states "Sponsors (guarantors) are presumed to be able to satisfy their undertaking if in the last 12 months they have had gross income from Canadian sources equal to the SUM of the amount shown in Table 1 and the amount in Table 2 below.".....does this mean I add the totals of the 2 tables.Myself,my wife and 2 children is $37650..then table 2 says "Additional Income Required by Sponsor to Meet Basic Needs of Sponsored Person and His/Her Family Members"....chart lists 3 differant amounts for those under 18 years old...$4133..$2865...$2151.Which amount d I use??
