Parking in Waterloo Region

[Markster]

But for many people the surface lots are closer to their workplaces, so they are preferable for that reason.

Yeah, that's going to be the main driving factor. The surface lots are smaller and more numerous, so they will usually be closer to your home/destination.

But yeah, it makes no sense that they have long waitlists for lots. If a lot is in that much demand, they should be increasing the price. An in-demand surface lot should cost more than a parking garage if it's really that popular.
