Found this pretty interesting, as I grew up with people around me calling them parking stalls, and used to call them that myself, but found that the more I interacted with people outside the province, the less I heard it from others.

This would also explain why "parking stall" rolls off the tongue more for me, as I've been using the term "parking spot" in more recent years, as that's what projects I work on call them, and it always feels slightly awkward saying it.
