About List A and medically important antimicrobials
List A names certain antimicrobial active pharmaceutical ingredients that are important in human medicine. We have put a number of measures in place to help limit the development of resistance to these medically-important antimicrobials (MIAs).
When used in animals, for example, ingredients on List A have restrictions around personal importation. There are also requirements for reporting sales of MIAs. These measures aim to protect public health and food safety.
List A includes:
- antimicrobials that meet the categorization criteria (category I, II and III) for MIAs or
- first in-class antimicrobial entities not yet categorized
Changes to List A
We make changes to List A as required, including when:
- Health Canada approves a new antimicrobial that meets the categorization criteria
- there is new information about an antimicrobial available on the international market
- there is new information about an antimicrobial already on the list
We will notify the public through a consultation on proposed changes to List A before any change is made.
Input from stakeholders and other members of the public is considered before we post a Final Notice to Amend List A. The Final Notice includes the List A changes that will take effect when it is published.
