In 2012, the Government of Canada and the Province of Alberta launched the Multi-Stakeholder Steering Committee on Drug Shortages to advance collaborative work on drug shortages.  To address this important issue, the MSSC brings together representatives from industry and health care associations, group purchasing organizations, distributors, the federal, provincial and territorial governments.  This multi-stakeholder approach is resulting in real progress in the communication and management of drug shortages.  Please see the links below for two MSSC tools:

  • The MSSC Multi-Stakeholder Toolkit (Toolkit) describes the Canadian drug supply chain, clarifies roles and responsibilities of key players, and identifies the tools and strategies available to address drug shortages at specific stages of the supply chain.  The Toolkit is a reference to support coordinated multi-stakeholder efforts to identify, mitigate, resolve and prevent drug shortages in Canada.
  • The MSSC Protocol for the Notification and Communication of Drug Shortages sets out clear expectations, principles and processes for how and when stakeholders across the supply chain share information in anticipation of or response to a drug shortage.    

Together with the earliest notification and information available on, these important tools will help strengthen Canada’s drug supply system and help all stakeholders better prevent and mitigate shortages.

The following information represents information supplied by pharmaceutical companies in Canada. This information will be updated as new information is known and available.

It is important to note that the information collected here represents a snapshot of drug shortages that are known to a Market Authorization Holder. This list will contain shortage information regarding medications that are licensed for use in Canada.

A pharmaceutical company who knows that they will experience important delays in supplying the Canadian market with an approved medicine to meet expected patient demand (i.e. normal prescription volumes) will report this as a 'drug shortage' on this website. A 'drug shortage' could be caused by

  • a problem with the maker of an active or key ingredient in a drug;
  • a manufacturing problem or issue;
  • safety issues identified at the place of manufacture (whether here or abroad);
  • an unexpected increase in demand for a specific drug;
  • regulatory delays in manufacturing site and/or health product approvals.

Delays in receiving prescribed medicines may be experienced in Canada that are not related to a manufacturer's ability to meet normal patient demand, but could be related to

  • unexpected increases in demand for specific drugs;
  • various interruptions in the normal delivery of medicines through the pharmacy supply chain and distribution network; or
  • factors outside the control of a company (e.g. natural disasters).

Members of the public who are experiencing an inability to receive the medication(s) that has/have been prescribed for them should talk to the health care professional who originally wrote their prescription (normally medical doctor, pharmacist, or nurse practitioner) or their pharmacist.
