Goku, the app is very well referenced and clear. I have collected reference letters from archives of every employer I worked for. The NOC5125 job, which was assessed against MI, was supported by reference letter that was signed by both HR head and my supervisor and sealed with the companies stamp. I also included the supervisors business card as well as letter of recommendation. The company is a leading translation agency and has a website and a large subsidiary network. The only information that is new to them included the names of my supervisors from other jobs and my most recent part-time job, which I assumed in Canada when I moved here. I cannot do any better than this
