Why have you deleted Curtis Road? It hasn't been removed as far as i can see in all the imagery options. Additionally, the paths through the forest shouldn't have been deleted either. They are also still visible.

The name of the track subdivison is incorrect. Metrolinx refers to this line as the "GO Subdivion" on official planning docs, not the Lakeshore East Subdivision.

This document from Metrolinx refers it that way multiple times

Page 46: "Trains to successfully incline from the GO Subdivision at Oshawa GO
station to climb and connect into the GM Spur"

It is a defining characteristic for Canada.

Take a look at Downtown Toronto. Sidewalks are everywhere, paralleling roads or not, with or without separation. By your logic, every single one of those should be deleted for being "redundant". Deleting these sidewalks is a loss of information for no good reason.

In hindsight, i probably shouldn't have linked the second wiki link, given it has a "dubious information" disclaimer at the top. It at least provides info that there are <1,000 instances of sidewalks being applied to the roadway as opposed to the >5,000,000 instances of separated sidewalks. I think that difference in numbers should more then justify separate sidewalks.

Please do not delete sidewalks for being "redundant". Sidewalks parallel to roads is a perfectly acceptable way to map them. Additionally, it makes them visible from the map itself as opposed to just adding sidewalk tags to the road.

This name change is incorrect and needs to be reverted. Official Metrolinx documentation addresses this stretch of track as the "GO Subdivision".

For example, the introduction on page viii of this document addresses it as such.

Why was 80 Bond deleted and replaced with an improperly formed building? All building parts must be contained within a building to show correctly. This needs fixing.
