Yes, your lender can refuse to renew your mortgage,  but they must inform you that your mortgage won’t be renewed well in advance of the term’s end date.  Lenders will want to keep their clients’ business if payments are being made on time. But borrowers who miss their payments regularly might find themselves without a renewal offer from their lender. In this case, the borrower must be given at least 21 days’ notice before the term expires.
