Vancouver used to have a huge number of downtown parking lots. This photo is from 1960:

There are other pictures that highlight the abundance of Vancouver's parking lots but this is all I could find while doing a quick search.
Many of the empty lots have been filled in but there are still a few stragglers.
This lot is perhaps the biggest lot left downtown. It used to be the site of a bus depot and has sat empty for many decades. There is talk the new art gallery could be built on this site:
