Hello Anon Hello Cosmo, there is a 14 day rule in the industry that almost all lenders adhere to. If the payment is late but arrives within 14 days of the due date no record of that missed payment is recorded. However if the payment is late past 14 days there is a record kept on file which never disappears. This can be a problem if in the future you are looking to refinance with that lender and they find out there are many lates on their file. They may just decide that they are not going to take a risk. The good news is that mortgages in Canada are not reflected on your credit bureau so if there is a problem another lender will not have access to this info and your approval will be based on your credit bureau instead. One thing to remember that banks will send the file to their legal department if a payment is not made after 60-90 days. Any legal costs the bank incurs (even if you bring the mortgage up to date) will most likely be forwarded on to you. Call the bank today and make sure they know of the situation, they may be able to help with programs like skip a payment, or extending your amortization to lower your payments. If you or any reader would like more information please do not hesitate to give me a call at any time.
