Large Cash Deposit

In April, I had to pay lawyer fees for my parents due to a case with the house. It was $35000 and it was made into a bank draft for the lawyers. My parents said they would pay me back. They have now accumulated the money and I can now deposit it at the bank. I know after $10000, the bank sends a notice to FINTRAC. I was going to bring a bank statement with the record of the bank draft on it as well as a letter from my parents. Would that be enough documentation or do I need anything else? The bank is TD if that makes a difference.
