I applied to the CAF years back. Went through an intensive application process that took almost a year. Multiple interviews. Aptitude tests. Medicals, etc.
I eventually got accepted on to start training as a Vehicle Technician. All I had to do was wait for the formal letter of acceptance.
However, when the letter finally came in, it seems there was one line in my medical file from my doctor that changed their mind and they requested that I see a doctor to be evaluated.
So I spoke to my doctor about the whole thing and after a good 15 minute chat, he wrote a letter of recommendation to the CAF stating that "that one line" was specific case that happened when I was a teenager and that I was good now.
Couple weeks went by and I got another letter that basically thanked me for my continued interest but that I needed to actually speak to the psychiatrist who put that one line into my file and have HER specifically say that I was good now.
After that - I was done. I wasn't jumping through hoops and over hurdles for an organization that cares so damn much about something so small.
