I went to a semi legit that had RMT neon sign. I got a receipt from them and submitted it to Sunlife. They contacted me shortly after and said no further receipts from that RMT for that place would likely be reimbursed. I now check with Sunlife first. The happy ending didn't end up so happy in the long run. I'm just glad they didn't call the housephone and leave a mesaage.
It is a very popular semi legit place. I only go there now with cash and don't ask for a receipt.
