MAK Immigration Data Observatory: Release 2

Replaced, November 3, 2026. A corrected version is at https://doi.org/10.5281/zenodo.23911007. This version's ledger file has blank dates on two records, and its description says the Change Ledger labels MAK-derived dates that the deposited files do not contain. The ZIP and its government values did not change. This version stays online for the record.

MAK Immigration Data Observatory: Release 2 preserves the Release 2 build published by MAK Canadian Immigration Services on September 9, 2026. The package contains normalized CSV and JSON datasets, source receipts and captures, Express Entry round-event history, dated IRCC/CIMM processing and service-standard snapshots, and a bounded 2026 public-policy Change Ledger.

Coverage includes study permit holders and prior study-permit/PGWP status to permanent residence from January 2015 to June 2026; study-permit and temporary-resident applications processed/finalized from January 2023 to June 2026; Express Entry round history through round 441 on September 4, 2026, with split identifiers preserved; processing/service-standard snapshots as of January 31 and February 28, 2026; and 17 source-reviewed 2026 public-policy Change Ledger records.

Government source values and MAK-derived calculations are labelled separately. Suppressed values are not converted to zero. Partial periods remain partial. Historical Express Entry rounds are not forecasts. Processing snapshots are not interpolated into a continuous series. The Change Ledger keeps listing, signature, effective, expiry and supersession dates distinct and labels MAK-derived or source-trigger-resolved dates.

Professional review provenance: Release 1 taxonomy and limitations were reviewed by Usman Khalil, RCIC R709592, and Omer Khalil, RCIC R710149. Release 2 underlying classifications, methodology and date/status/supersession resolutions were reviewed by Usman Khalil, RCIC R709592, approved September 9, 2026. This is descriptive research infrastructure, not individualized immigration advice, a prediction tool or government endorsement.
