East of Donlands the former border is the most obvious through the former street signs. All the houses on Milverton are in Toronto while those on Springdale are in East York. The housing stock is practically the same though. Some differences are the streetlights as noted (white for Toronto, with Donlands the most obvious example IMO) and sidewalks - common for East York side streets to have a grassed boulevard between road and sidewalk whereas the sidewalk abuts the curb in Toronto. Certainly there are exceptions like my own street but these two traits let me when I’m crossing (former) jurisdictions.
