Names seen in certificate transparency logs and confirmed in DNS, as of Oct 22, 2026. A floor, not a count of the TLD: a name that never appears in a certificate is not here, and we hold no zone file for .ca. The registry’s own figure is the count; this one says how much of it we can see name by name.

Aug 2026: 3,539,669 — third-party estimate; the registry has not published that month yet.
