That's terrific news! The RDSP is a very good vehicle, once set up. There is an equal amount of paperwork if you want to claim the provincial support, or CPP disability (after a person has contributed and then is disabled).... but I believe you can only get the RDSP after you get the disability tax credit paperwork done, too, so I hope that will help with your own taxes.
For others looking into this -- if you are an adult and did not claim RDSP, and your medical reports / forms state that the disability was present in prior years, the government will help you to get retroactive payments for prior years. Yeah, there is a wait / delay, but it eventually works, once all the correct and approved paperwork is in place. It's not too late!
RDSP:
Canada Disability Savings Grant
The Canada Disability Savings Grant is a matching grant. That means that the Government also pays into your RDSP to help you save. The Government gives matching grants of up to 300 percent, depending on the beneficiary's family income and contribution. The maximum Grant amount is $3,500 per year, with a limit of $70,000 over your lifetime. Matching grants are paid into the RDSP on contributions that are made up to and including December 31 of the year you turn 49 years of age.
