Master Numbering System (MNS)

Data under review

This data is not available right now. We are reviewing the data to determine if it can be made open to the public.

This system maintains the master institution numbers for all Ontario health care facilities including hospitals, long term care facilities, community health services, and others. The MNS files are used by many of the Ministry of Health and Long-Term Care (MOHLTC) systems for the production of reports and for publishing an annual Code Book. Each organization has been assigned a unique four digit identifying code. The Master Numbers are also used by the Canadian Institute for Health Information in clinical data reporting.
