Rows for us and OpenAddresses are sums over sources and double-count where sources overlap (regions and their members). The municipality matrix below takes the max per municipality for us instead.

Coverage by municipality

414 lower- and single-tier municipalities (LIO polygons). Points binned by polygon for us and Overture; NAR and ODA by census-subdivision name.

	Ours	NAR 202606 rows	NAR locations	ODA 2021	Overture 2026-10-21.0
Municipalities with ≥1 row	269	414	414	161	392
Rows binned to a municipality	5,116,068	6,211,604	4,162,913	4,029,086	5,424,604

NAR and Overture rows are unit-level (one row per apartment where StatCan knows it). "NAR locations" counts distinct LOC_GUIDs, the building or entrance. Our layers sit anywhere between the two: some publish one point per building, some one per unit, so Ours / NAR loc. is a scale check (is the layer the same order of magnitude as the register?), not a completeness score. Well over 100% means a unit-level layer, well under means a thin one.

165 municipalities where we hold under 5% of the register's locations (nothing, or only spillover from a neighbour's layer): 378,572 of 6,211,604 NAR rows (6.1%). Highlighted below.

Reserves and unorganized territories have no LIO polygon and are expected here. A municipality name here means an alias is missing in muni_aliases.csv.

Unit fill is a property of the source as much as the pipeline: a city that publishes one point per building has few units however well it is read. Compare a source against the same jurisdiction below, not column against column here. We carry no postcode field.

OpenAddresses, source by source

85 Ontario address sources in OpenAddresses' batch service: 84 current source files with an addresses layer plus the retired peterborough entry its history still carries (Mississauga's file has buildings and parcels only, so it is not here). 21 have not run successfully in 60 days. Join to our datasets is hand-kept in oa_sources.csv. "Our changes" is how many of our last 30 daily pulls brought different content: the source's own churn.
