My first response would be to ask WHY they want each of those. They may have a reasonable (though misguided) answer.
THEN, inform them they will receive a receipt at year end with your SIN and other needed information. Tell them who (as in my husband, a child) live with me but they do not need any more than that. Your drivers licence serves them no purpose.
They should have asked for this before beginning care with you.
Do you have a contract with them? It sounds like they feel you are working for them. This is not going to work long term. They need to understand you work for yourself and they are your clients and they need to respect the terms you set out.
