Post-Notice of Compliance (NOC) Changes – Quality Guidance 

From Health Canada

Appendix 2: Quality post-NOC changes of veterinary drugs of this guidance has been updated and superseded by the Post-Notice of Compliance (NOC) Changes: Guidance for quality of veterinary drugs as of August 28, 2023.


The Post-NOC Changes: Quality guidance assists sponsors with the classification of quality changes made to a new drug that has received a Notice of Compliance (NOC). It also provides sponsors with recommendations on the data to support a change which would be considered sufficient to allow a determination of the impact of the change on the quality of the new drug as it relates to safety, efficacy and/or effective use of the new drug.

Please note, Health Canada has taken a first step to simplify market access for non-prescription drugs. For more information visit, Non-prescription Drug Action Plan
