All corporations are required to file an information return for the enterprise register. However,

• if the information in the enterprise register is correct, the corporation need only check the box provided for this purpose on form CO-17.SP, Déclaration de revenus et de renseignements des sociétés sans but lucratif (see courtesy translation CO-17.SP-T), or form CO-17, Déclaration de revenus des sociétés (see courtesy translation CO-17-T), as applicable;
• if the enterprise register contains incorrect information, the corporation must use the Produire une déclaration de mise à jour annuelle online service, available on the Registraire des entreprises website.
