Which Medications Are in Shortage in Canada Right Now?

1There's no single fixed list — check the current status directly

Drug shortages in Canada change constantly — a medication can move from adequate supply to active shortage to resolved within a matter of weeks. Any list of "current shortages" that isn't pulled live from an actual database is likely out of date by the time you read it. The most reliable approach is to search the specific medication you're asking about, either by brand name or by DIN, and check its current status directly.

2Some drug classes go into shortage more often than others

A small number of drug categories account for a disproportionate share of Canadian shortage reports — worth knowing about even if you're not currently affected, since it means checking status before you're down to your last refill is a reasonable habit for these specifically:

• ADHD medications — stimulant medications have been affected repeatedly as prescribing volumes have risen sharply over the past decade.
• GLP-1 medications (Ozempic and similar) — demand has outpaced manufacturing capacity at various points, causing the supply to cycle in and out of shortage rather than resolve permanently.
• Amoxicillin and other common antibiotics — shortages tend to cluster seasonally, around the respiratory illness surge in fall and winter.
• Insulin — periodic shortages of specific formulations, including some older animal-derived insulins.

3Manufacturing disruption is the most common reported cause

Across reported Canadian shortages, manufacturing disruption is consistently the largest single reported cause — more common than raw material shortages, demand spikes, or distribution issues. That matters for expectations: a manufacturing-related shortage often takes longer to resolve than a short-term demand spike, since it depends on a production line getting fixed or requalified, not just restocking a warehouse.

4Where the official data comes from

Manufacturers are required to report actual and anticipated shortages to Health Canada's Drug Shortages Canada system. MedShort pulls from that same official reporting system rather than maintaining its own separate assessment of what's short-supplied — when you check a drug's status here, you're seeing the same underlying report a pharmacist would.

5What to do once you know your medication is affected

Checking status is the first step, not the last one. If your medication comes back as an active shortage, the next move is a conversation with your pharmacist about your specific situation — not switching anything on your own. See the full step-by-step guide for what to ask and when.
