Hi, can anyone help me with my situation? I have the code error 15, although I don’t even have my cra account yet, since it’s my first time filling, I’ve called them yesterday and they said that since I dont have an account, they cannot unlock it since I don’t possess one, why am I still getting this error 15??

@Babli You must print and mail your return to the CRA if they are unable to unlock the account and they do ... If the CRA has nothing on file for you, they will not accept an electronic filing.

My CRA Account is unlocked and I can access it.  What to do now?

If your MyAccount is locked, then you will also need to contact the CRA.

"Contact the CRA"  Seriously?  Good luck with that.  {-)  The CRA's phone system is utterly terrible, lots of circular loops, some entered commands don't work, often hung up on....  And if you finally get through, as I did on a 4th attempt, you'll have to wait a  L__ O__N__G  time, so don't phone late in the day because you might never get through.

@user17728281989 We are sorry that your experience with the CRA is less than optimal. Usually first thing in the day is better. 

Unfortunately, your suggestion isn't helpful at all because it doesn't address CRA's need to fix it's phone system. or to improve NETFILE submissions to determine actual causes of failures to submit.  As a start,  I would like the CRA's phone system to, if/when, you finally get through as a first choice to offer the caller a 'call back' so they're not on hold for one hour+.  I called CRA again yesterday and when I finally got through and waited for about 10 minutes, I was thankfully given the option of a 'call back' which I selected.  About 1 hour later I got a call and the employee, after speaking with me for about 5 minutes mostly about checking/re-checking my credentials and sending 2 factor codes... finally said she was unable to unlock my NETFILE access or help me.  She said she was going to transfer my call to an available employee who could help.  I said "Wait! I've been dealing with your system for about 1.5 hours now what happens if your phone transfer fails and I have to wait again? "  She said, "Don't worry the transfer will work and you'll be connected with the employee within seconds."  Well, it didn't work....(an employee can't transfer a phone call correctly?)  So I waited nearly another half hour and was connected to an employee named 'Daniel'. who was very helpful.  He quickly unlocked my NETFILE access (it locks after 5 failed submission attempts) and was ultimately able, because he was obviously knowledgeable of the system,  to find the error in my tax return.  The problem when attempting to electronically file a tax return that gets rejected is that the rejection notice does not specifically state where the error in the return actually is.  So you're left guessing and going back through all the input fields hoping to find where you might have made an error.  Fortunately Daniel knew his job very well and had a couple good hunches of what might have been causing the problem.  And he was correct! So the NETFILE submission was successfully submitted.  Please make Daniel the head of the department, or at least increase his salary, and put him in charge of teaching the staff their jobs.  Thank you....
