I believe that is a Remington Sherman door having seen pictures of one just like it, but as you say it is strikingly similar to the Cleveland York. I, too have found nothing in the patents for either door. If I remember correctly, York did take over Rem Sherm but that happened later. The overall design of both doors was both innovative and more modern looking than other doors of time, especially if the Toronto door is from 1914. Both doors use pins in the jamb that mate up to pins in the door to push and pull the boltwork. There is definitely a connection between the two but I have yet to figure it out.
