Another Toronto Public Library (TPL) user here. Selection of eBooks is somewhat limited (lots of romance and mystery in fiction), but they do seem to get new titles added fairly regularly. I've been borrowing a lot of non-fiction eBooks. So far, with the books I've put on hold, I've been able to get them faster than if I had the hard copy version on hold at the same time. TPL allows you to have up to 10 eBooks on loan at any time.
Most of the newest books seem to be available as ePUB, which I also prefer to the PDF format.
Even with the limited selection, access to library eBooks is one of the biggest benefits I've found for having a Kobo eReader. No more late fines!
