Visiting the old farm site. It was certainly challenging to identify the location of the farmhouse and barn. Dad is standing on what may be the farmhouse location.
I was researching aerial photography in Durham Region and came across Global Air Photos. They have an online archive of aerial photos, all watermarked of course, but accessible for browsing which is amazing in itself. The above photo shows the western part of Whitby in 2006, and in the very bottom right-hand corner is the Mackey Farm! I was pretty shocked, that the only photos they have of Whitby pretty much all circle the farm. The photos also feature the four high-rise apartment buildings that have been there for as long as I can remember, perhaps foreshadowing the farm's sale and the surrounding residential growth when they first went up. Thanks Global Air Photos...wish I could afford you, or one of your flights, and have kick-ass photos/video for the film!
