Same here in Canada. I think its legitimate learners. Not sure why you think age has anything to do with it, theres no max age to learn to drive. Hell, my late grandma didn’t get her licence/learners permit until she was in her 60s.

Could be related to an influx of immigrations as well, plenty of people didn’t have the luxury to get a drivers licence or own a vehicle.

That or people are just too lazy to remove them haha.
