CER Assessments Map Service (Federal Geospatial Platform)

The CER's Environmental and Socio-economic Assessments (ESA) layer, published through the Government of Canada's Federal Geospatial Platform at maps-cartes.services.geo.ca under the NRCan folder and served in English and French. Two protocols are exposed for the same data and both answered anonymously on 2026-07-27: an Esri ArcGIS REST MapServer (?f=json returned a service description naming the CER as the data owner) and an OGC WMS 1.3.0 endpoint whose GetCapabilities document parsed as valid XML. This is CER data on federal shared infrastructure rather than a CER-operated host, and it is the only place in this review where an open, vendor-neutral international standard (OGC WMS) is used.
