Walk into HSBC head office and ask - they will explain it to you.
Having said that, you are calling 10,000 (currency irrelevant) a large sum and unfortunately it isnt. Thats a tiny amount and I think you should just transfer it once, pay the paltry $40CAD total fees and get on with life instead of worrying about doing this drips and drabs.
Since TD requires you to be there in person to initiate the transfer, go and talk to these guys, they may be able to help you:
