Every effort has been made to ensure the accuracy of the information contained in this website. However, TransCanada is required to file its Tariff and all amendments with the Canada Energy Regulator (CER). The documents filed with the CER constitute the official version of TransCanada’s Tariff and are conclusive in the event of a discrepancy between the filed version and the version on this site.
