I am fairly certain that the building in the middle of the image is the Port Union Cafe. Can barely make out the sign on the right side of the building (facing north). This is where Trinity Pub sits currently. Road running horizontally is Route 747 and Port Union road would run east/west (down/up) to the left of the photo. The small trail behind the cafe, going off to the right behind the tree in the middle-right of the photo is now a walking trail that takes you over to Seward Road.
