Disability Benefit question . Back pay?
My son just turned 19. We finally got around to do his taxes. My son is severely disabled- he has a rare genetic disorder called Trisomy 17p. Along with ADHD and mild form of OCD. I was just wondering if he’ll get back pay for The Canadian Disability benefit- he has had the DTC since 4 and we have an RDSP set up for him. Does it go back a year? Does GST as well? He finally got his PWD here in BC . He lives with me full time. Thank you
