Is the account number you entered 10 digits or 9? Sometimes only the first 9 will show up on your bill as the 10th is an optional number that some banks require for online payments but not all. If you log on to your My Account page to view the bill online it will show you the 10th digit there. The TD error may be due to a missing 10th digit.
The likelihood of someone who works for TD chiming in here is a bit less than zero. It is recommended you contact Telus for a 10 digit account number, or confirm through My Telus of a 10 digit number for your account as previously mentioned.
Alberta Treasury Branch customers have a similar issue.
