Don't stress yourself, the current system allows working in a profession other than your degree. I don't see why they won't continue that.Since the new NOC system will be introduced, should people like me give up all hope? I have a Masters in a different field but I worked in a NOC B occupation for one year, a few years back. I spent 3 years learning French and it will be such a slap on the face to know that now you need formal education in the field you worked in. :'(
