[News](https://www.payments.ca/insights/news-research?field_article_type=24) # Payments Canada publishes Lynx ISO 20022 corporate to bank message guidelines April 26, 2024 Payments Canada, in collaboration with its members, has created [guidelines](https://www.payments.ca/payment-resources/iso-20022/high-value-payment-system-lynx) for using ISO 20022 messages between corporates and banks for Lynx payments. These guidelines can be referred to as best practices for implementing ISO 20022 messages pertaining to Lynx payments between banks and their corporate clients. The guidelines are designed to be in alignment with both the Lynx ISO 20022 interbank messages and global best practices. In March 2023, Payments Canada introduced the 2019 version of ISO 20022 messages for Lynx payments in the interbank space. However, the use of ISO 20022 messages between the banks and corporates remains less prominent to date and, if used, is limited to older versions of these messages. The newly created guidelines will help facilitate consistent usage of ISO 20022 standard for the end-to-end Lynx payment flow, representing a significant step forward in modernizing the payment experience in Canada. The current message portfolio of these guidelines includes five messages: two payment initiation messages and three messages pertaining to account and transaction reporting. These guidelines also reflect Payments Canada's commitment to enabling consistent usage of ISO 20022 messaging.
