Disclosure timeliness

Lobbyists must record a communication within 3 days. lobbyTO measures the gap between a communication's date and the first daily snapshot of the registry export in which it appears. The export refreshes daily, so a 1-day gap is expected.

Measurement in progress. Daily snapshots began on 4 October 2026 (2 days of snapshots so far); results appear after 6 months of snapshots, from 4 April 2027. Communications dated before the first snapshot are not measured.
