I have been learning quite a bit about RDSPs over the past few months -- completed a webinar, reading, discuss -- this has always seemed so complicated to me! Finally! Clear, plain language, completely comprehensive information! If you have a disability, or you have a friend or family member with a disability, please take a look at this website.
This web site has information about the Registered Disability Savings Plan in Ontario and includes a step-by-step guide to becoming eligible, opening, and managing an RDSP.
