Untagged bag put on to luggage belt in Toronto Pearson after US customs cleared

The other day, I was on a flight from Toronto Pearson (YYZ) to Chicago O'Hare (ORD) with one checked bag.

I checked in online earlier and had my boarding pass with me. It completely slipped my mind that I need to print my luggage tag at a kiosk before heading to U.S. customs clearance area.

I cleared customs, and those familiar with travelling to Pearson would know, you then head over to drop your bag off and go through security.

At the time of dropping my bag on the luggage belt, there was some airport staff but no one cautioned me about the bag not being tagged. I got to Chicago, and sure enough, no bag. That's when it all sunk in.

I filed a report at the Air Canada baggage office in Chicago and I have a file reference #. I've identified contents of my bag- however, it's been 3 days and still nothing.

I suspect my bag will have stayed in Toronto and so I am hoping that upon my return to Toronto, I might be able to make some progress.

Now, for my questions:

1. Is there some additional steps I should be carrying out to facilitate the process and improve the chances of getting my bag back?
2. Am I eligible for compensation from the airline (Air Canada) given that it is partly my fault for forgetting this step?

Edit 1 (day 3): I spoke to lost & found at Pearson and they told me that bags that go on to the belt don't typically reach them and that SwissPort (they handle baggage) might be able to shed some light

Edit 2 (day 4): I contacted Swissport Baggage Services (905 694 1736) and got voice mail. Called Swissport and they told me "Air Canada handles luggage for T1 even if it was untagged" and to contact AC

Edit 3 (day 5): I contacted Swissport again to see if I get the same story from the previous day. It turns out Swissport handles baggage for Terminal 3 and that I have to contact Air Canada directly

Edit 4 (day 5): I went to the airport to see if I can find the bag at Air Canada lost and found. They brought me to a room that had untagged bags and it wasn't here. I will now fill out a baggage declaration package and the chances of recovery are slim
