Transferring agents, financial institutions, and stock issuers may require a Lost Document Bond when they issue a new document, such as a stock certificate, corporate debenture, government bond, warrant, life insurance policy, cashier's cheque, or bank draft, to replace a document that was misplaced, lost, or destroyed. Lost Document Bonds are also called lost instrument bonds or lost security bonds. Fixed Penalty Lost Document Bonds are required when replacing documents, such as Canada Savings Bonds, that have a fixed, non-fluctuating value.
