Two of the trees in the October, 1913 picture below are definitely still there. The perspective in that photo no longer exists, because of trees there now, though.
A couple of others near Carlaw and McConnell are probable matches, but I'm most confident about these two:
(1) is one of the large trees which were transplants in 1913 - in the photo below, it's supported by planks. It's now just to the west of the older park house, which didn't exist when it was transplanted. It has a very characteristic thick branch pointing off to the north, which makes identification easy.
(2), a maple near the front door of Holy Name, which faces Carlaw, is an interesting case - it's already a mature tree in 1913. My theory is that it was planted in maybe 1880 to shade Carlaw when it was still a country sideroad. There are a couple of very old maples on Carlaw above Gerrard - there's an enormous one in a front yard at Carlaw and Langley, and I wonder if they weren't originally rural shade trees.
