Demand that ODSP payments to the disabled include annual cost of living increases

Demand that ODSP payments to the disabled include annual cost of living increases
Why this petition matters
My son is disabled and receives Ontario Disability Support Program (ODSP) payments. Unlike my Old Age Security (OAS) and Canada Pension Plan (CPP) payments, my son's ODSP payments are not indexed with annual cost of living increases. He has received the same amount of ODSP payment each month for all of the years since he was first approved by the ODSP.
This seems extremely unfair, since the cost of living increases affect all individuals in Ontario, not just the ones that are not on ODSP.
Unfair treatment of any kind needs to be addressed. I am asking that the Ontario government change the way ODSP payments are calculated so that all disabled people on ODSP will have an annual cost of living increase in their ODSP payments just like OAS and CPP payments.
