You cannot claim an eligible dependant tax credit for your son. As per CRA, your son must be under 18 years of age or had an impairment in physical or mental functions if you want to claim an eligible dependant tax credit for him.
However, your child can transfer his tuition tax credit to you. Your child must first claim the tuition amount on their own tax return. If there is any amount left over after your child has claimed the tuition amount, they have two choices: transfer it or carry it forward.
