A cleared scan of the picture of Edith Nicholson and teachers at Westmount Methodist.I checked with another picture and the man at right is certainly Dr. Villard and these are likely the Institute grounds. The pointy buildings at left are still there on Staynor.
The MAAA grounds are on the other side.
The Westmount Methodist building is gone now. A playground is there now.
The first chapter of Up to the Light, by Paul Villard describes the building: A solid large brick building composed of the main building and two wings, behind which is a ground for recreating.
In the basement of the main building are found the kitchen and apartments of the servants; on the first floor the Principal's apartments and teachers' parlour and pupils reception room. On the second and third floor the girls' rooms and on the fourth floor, the infirmary.
In the basement of the South Wing is the school dining room and on the first, second and third floors are the boys rooms.
In the basement of the North wing are the laundry, coal bins and furnaces. On the first floor the recitation rooms, on the second floor the chapel.
No mention of where Edith's rooms would be. Probably with the girls.
Edith looks young in this photo. It is not often that the photos capture texture, but here you can see her smooth, young skin and the pattern on the shirtwaists.
