supplement payments (ftb reco amounts) will be paid again at tax time

your PPS friend would have automatically received hers each year somewhere between mid july and mid august. the only way pps customers dont' receive that amount each year (around 600 per child for ftba, 300 extra per family for ftbb) is if they've received an overpayment - which generally relates to getting more maintenance during the year than what they initially were told they would (ex gets a better paying job etc)
