In the first attempt I've sent them 2 reference letters, job contracts, copies of my SIN-like document where all my jobs are listed, everything I could.
Well, first job had only 9 months. Second one exactly 1 year. I've worked for a 3rd company for way longer than those two, but the HR never helped with any document about them, so I felt like sending with what I had as evidence. They sent me a letter with the "work experience" text-marked, but no comments about it, so from what I can understand maybe it was not enough for them...
I was already waiting for it, so I wrote these 2 new letters about this company and asked the HR for phone numbers on which they can confirm the information, not my job duties, but that I work for them at least.
It's funny that I work since 2005 but can't really prove it if the HR won't help me out. I look like a newbie for CIC...
