MOHLTC LHIN Sub-region Boundaries Geographic Information (recommended)

Data Format(s): File Geodatabase and PDF

In response to the MOHLTC’s Patients First Strategy, LHIN sub-regions were developed and defined by the individual LHINs in late 2016 to plan performance improvement and service integration at a community level. The MOHLTC Sub-region Cartographic Boundary File is an ESRI geodatabase / layer file that includes the boundaries for all of Ontario’s 76 sub-regions for use in Geographic Information Systems (GIS). This file should be used for the display of sub-region boundaries and not to select Census geography for analysis. In October 2016, each LHIN submitted a Guide to Formalizing LHIN Sub-Regions to the MOHLTC. This document included a description of the geography of the LHIN’s sub-regions. HAB used these descriptions to build geographic boundaries using standard 2011 census components (Census Subdivisions and Dissemination Areas), or used the GIS files supplied by the LHIN. In more rural areas of the North East and North West LHINs, sub-region boundaries are not based on Census components because it was not possible to create large contiguous areas. HAB worked with both LHINs to refine the boundaries in these areas. Since this boundary file does not correspond to Census geography in all areas of the province, we refer to it as a ‘cartographic’ file. The file is supplied as a polygon feature class in an ESRI File Geodatabase (FGDB) or as an ESRI Shapefile. The co-ordinate system of the file is GCS North American 1983. Field descriptions and additional information are included in the FGDB or Shapefile metadata.
