Hi -- thanks all the detailed surveying you're doing in the GTA!

Quick note about the change to surfaces here. You've added surface=concrete:plates to the sidewalk. This value actually refers to prefabricated concrete plates that are made offsite and then trucked to where they are needed and placed with a crane.

The vast majority of concrete sidewalks and paths in Ontario are instead poured in place: liquid concrete is poured onto the ground in between formwork, then once it hardens, control joints (for stress relief) are cut into it. This gives the appearance of separate "plates", but the plates might be different lengths and they don't have eyelets they would have been lifted with. So I think surface=concrete is the better tag?

See https://wiki.openstreetmap.org/wiki/Tag:surface%3Dconcrete for details and photos. Let me know if this makes sense or if I have something terribly wrong!
