I had the same issues, unfortunately I had to call pretty much all fn day to get through
I buckled down and just kept redialing yesterday. After 2 hours straight, I finally got passed the auto hang up queue and into the actual wait queue! 45 minutes on hold there, then I got through to someone! But I guess it's a bit different process in Ontario. The agent couldn't approve my PAL and had to send an inquiry off to the CFO. Hopefully something finally happens with my application!
