Glad everything worked out in the end!
We had a similar problem when we first got our mortgage. We had to go through the mortgage center in Cambridge to get our mortgage ( DON"T GO THERE). On the day we were getting our keys and signing the last of the paperwork the lady at the bank (scotia) saw that most of the numbers were off.
The guy at the mortgage center had our downpayment off by about $45,000, The cost of the house was off by $30,000, the address was wrong and numerous other things. Luckily from the great service at scotia we were in the house at 11:30 that night!
