Methodology
Every number on this site is FOI-sourced, cross-verified, and independently auditable. Our methodology follows rigorous health data principles.
Primary sources only
FOI responses, FAO reports, MCCSS publications, Hansard, and budget estimates. No secondary interpretations without primary source verification.
Citation protocol
Every data point includes source document, date, FOI reference number where applicable, and page number.
Cross-verification
Numbers cross-referenced against multiple independent sources (FAO vs. MCCSS vs. budget estimates vs. Statistics Canada).
Update protocol
Data pages include "Last verified" dates. Stale data (>90 days) triggers automatic review.
Correction policy
Any errors identified are corrected with transparent changelog. No silent edits.
The standard we set
89,799 children are registered. 20,633 have active funding. 23% are receiving core clinical services. Every one of these numbers traces to a specific FOI response or government publication, verify any of them.
The numbers are real
Commitment to Accuracy: Our data is verified against official government reports (FAO, MCCSS), peer-reviewed scientific literature, and accessible public records. Last updated: March 24, 2026.
