Nasdi, sometime last June I had requested my notes, and shockingly, they sent me someone else's. I wrote back to them at ATIP-AIPRP@cic.gc.ca to tell them of their error. They replied 8 days later, apologized, and said they would send my notes the same day, which they did. I still can't believe they sent me some other person's notes....and they weren't even for a CEC application.
So if they don't respond in about 10 days, write to them again. Plus, make a second request for GCMS notes online. I know there is also the option to file a complaint, but I don't know what that does or how long it takes.
