Any pharmacists here to answer a prescription payment question?

Heya friends! I've been picking up a recently prescribed medication for the past 2 months, and had to pay a small portion of the total, which I was totally ok with and had budgeted for it moving forward. I just picked up my third month today and got a nice little surprise when the pharmacist said I didn't owe anything.

Right above the barcode, I see abbreviations CF/AS/VO/IC/CA, and below it, there's a breakdown of which of those abbreviations covered how much of the total. Both me and my wife are well insured through our own and each other's employment insurances but I was curious what those abbreviations mean and which of them is mine, or hers, or provincial etc. I can't find any information on this online.

My first thought was maybe because of the new year, the quota reset and that's why I might not be paying but neither one of us had anything prescribed last year so it wouldn't have filled up anyway. Any ideas?
