How rxstat works

Source. All report data comes from Health Product Shortages Canada, the mandatory reporting database operated for Health Canada. rxstat syncs continuously through the day.

Aggregation. The official database files one report per product per company. rxstat groups every report by active ingredient (using Health Canada's own ingredient grouping) into a single page per drug, and computes a plain-language status: widespread when half or more of reported products (or any Tier 3 report) are affected, partial when at least one is, anticipated when manufacturers expect a shortage.

Change tracking. rxstat snapshots every report on every sync and records the differences: status changes, resolutions, and estimated end dates that move. That history powers the timelines and the "estimates have slipped" notes; the official database does not display it.

Honesty rules. Estimated end dates are manufacturer self-reports and are labelled as such. Counts reflect products that have filed reports, not the entire market. When we don't know, the page says so.
