You're mistaking it for two different things.
If you submit an air safety report at Air Canada you will not be disciplined. I've been the chair and the vice-chair for the last six years. I'm usually the guy who calls you first when something happens in the middle of the night. I go with you into the interviews. With Air Canada they have a very robust reporting system. If I write an air safety report, if I self-report, I will not be disciplined.
