Tier 3 Drug Shortages

Tier 3 drug shortages are those that have the greatest potential impact on Canada's drug supply and health care system. Impact is based on low availability of alternative supplies, ingredients or therapies. The Tier Assignment Committee (TAC), composed of federal and provincial/territorial governments, healthcare professionals, and industry stakeholders, makes recommendations on the tier assignment of drug shortages. The TAC assessment includes:

• a review of the information gathered on the shortage issue, and
• a thorough discussion on its potential impact and next steps.
