Here are a couple of great pictures of a home on Wellesley Street East as it appeared in 1939 along with how it appears today (not there!). The home on the right in today’s Google Street View is 438 so I suspect that 436 was knocked down since the laneway appears wider than it did in 1939.
436 Wellesley Street East – Front View in 1939
436 Wellesley Street East – Rear View in 1939
*an earlier version of this post suggested that 436 had been possibly renumbered to 438, but I later realized the width of the laneways make it more likely that 436 was demolished.
