No, unfortunately it's just one number per account. Years ago they started advertising that you would be able to purchase additional numbers to add to your account, but after a couple of years they just took the advertising down.
If you just want a number in a different province to ring your home number, one way might be to set up the second number and then forward it to your actual number. Just remember that the account deletion rules will apply to the second account (
