So I'm due to receive some money back as the CRA has assessed my prior returns in my disability tax credit application.

But for a good part of the past 10 years I wasn't working so I don't get anything back for those years. I'm aware I can transfer the unclaimed amounts to a supporting family member but wondering who it should be? I live with my mom, sister and husband and can I transfer to more than one person in order to max out the credit?

How do I go about requesting a transfer for the retroactive years? The CRA is kinda vague on their websites about what they want me to put in the letter? Hoping somehow can help as the whole process is kinda confusing.
