Gaps over time

How many Toronto Centreline local streets are still missing from OpenStreetMap, and how many named OSM streets are extra (no TCL street by that name) — one point per daily comparison, so a mapper can see the worklist shrink.

5 comparisons from 2026-05-01 to 2026-10-31 · today's gaps · data (JSONL)

Points in the shaded span are reconstructed from earlier published pages: each is the last page this repo committed for that OSM extract, read back from git history, so it counts under the comparison rules of its day. The rules were still being tuned then (street-name normalization, which road types count), so a step between early points can be a rule change rather than mapping. The rest were recorded by the comparison itself. Counts move when the City edits the Centreline, not only when someone maps.
