2014 Residence Coding System

Effective April 1, 2014

The Ministry of Health and Long-Term Care Residence Coding files presents a classification system for patient residence information. This coding system provides a framework to determine referral patterns to various health care facilities as well as a means to determine the geographical spread of diseases.

A unique four-digit number has been assigned to each municipality and populated Indian Reserve or Settlement in the province. Where an area is not municipally organized, the four-digit number referred to one or a grouping of census enumeration areas.

The first two digits of the code represent the geographic county, district or regional municipality in which the place is located. Digits three and four identify municipalities within the county, or areas of the county if the area is not municipally organized, or Indian Reserves and Settlements.

The importance of correct coding cannot be over emphasized. Residence Coding provides part of the basis for hospital and other facility's planning and funding, as well as a crucial part in disease surveillance, public health expenditures, physician referral patterns and other community based services.

Alphabetic Listing

The manual contains place names in Ontario listed alphabetically with code numbers, and also code numbers for all other Provinces of Canada, the States of New York, Minnesota, and Michigan, U.S.A. Remaining, and World Remaining.

Numeric Listing

This section is organized in ascending residence code order and is headed by a Regional Municipality, County or District for the Ontario codes. Only place names with a type of place assigned are listed (for Ontario).

Please note that due to space limitations on field lengths, some municipal names have been truncated or abbreviated and do not necessarily constitute legal names.
