The Canada Revenue Agency (CRA) NETFILE Service is shut down for it’s annual maintenance. It will open on Monday, February 21, 2022 at 12:00:00 a.m. Eastern Standard Time. You’ll be able to file or print after then.
Though the vast majority of forms will be ready for Monday’s NETFILE opening, some may still not be finalized. Please see this TurboTax FAQ for more information: Why does TurboTax say my forms are locked or haven't been finalized?
