I'm often in that area, as I cycle on the sideroads during the Summer. I see the changes first hand. Your photos depict the urban sprawl beautifully.
If you remember what Elgin Mills and Woodbine looked like just a few years ago. One year you had the driving range just north of Woodbine at Elgin Mills bustling with golfers, the next year it's abandoned (sold).
Not only are there For Sale signs on Woodbine, but if you continue North on Warden, McCowan, Kennedy, you'll find parcels of land for sale and itching for development.
