Critical (Tier 3) drug shortages in Canada
Health Canada assigns Tier 3 to the shortages that matter most: drugs with few or no alternatives, serious indications, or system-wide consequences. These get coordinated national attention, and they are the shortages most likely to reach the news. If a medication you take is on this list, talk to your pharmacist or prescriber early rather than at your last refill; our guide on what to do in a shortage covers the practical steps.
