The Health Products and Food Branch (HPFB) will be updating master file (MF) registration as a part of the continuing effort to implement a common intake approach for all drug product lines, including veterinary drugs. MFs holders and applicants using MFs to support veterinary drug submissions will need to submit MF transactions via the Common Electronic Submission Gateway (CESG) using an application form in Extensible Markup Language (XML) format. This update is consistent with the transition of human drug MFs application form to a web-based form effective June 26, 2023.

Additionally, HPFB is consulting on a proposal to implement fees for MF for veterinary drugs, to align with the existing MF fee structure for human drugs. Comments on the MF fees proposal will close on August 12, 2023.

Both changes for veterinary drugs are proposed to go into effect January 2, 2024.

Important information
