What happens to your existing work permit if you get Open Work Rights via APRC?

I was told the same thing. They told me that the OWP is built into the APRC. No need to have the 2 together at the same time. I pressed the issue more and they stood their ground. Would not even let me apply for one. A higher up in the office came over and told me that soon, the OWP will be done away with altogether (as far as paperwork goes) and the APRC is all you need. They were nice about it though.
