How to look up a building permit in St. Catharines
St. Catharines publishes its permit records itself, on a ArcGIS FeatureServer open-data endpoint at services6.arcgis.com, in the dataset "Building Permits Public". That feed is the source this page reads, so a record here can be checked against the city's own copy. Search by civic address first, then confirm the permit number and the issue date. Records the city has not yet published will not appear in either place.
