Same here.. locked forms.  Big inconvenience.. 30 min wait with customer services - not eta or updates provided online .. I have a standard tax return (very easy to do online) and still no communication with customers .. but they will gladly take your payment before you receive the locked forms messege

There are no locked forms, you will need to make sure that you update your software. 

I have updated my software but everything is showing as locked after I downloaded my T4s from the CRA site.
