I was using Geocoder.ca for around two months for a project at my current company. We were trying to work with weather stations and weather data for specific stores in countries like El Salvador, and we used Geocoder.ca to fetch the locations for those weather stations.
Because some of these weather stations were in quite remote locations, Geocoder.ca definitely helped me save time and speed up my development process by fetching the information that I needed. It was used for on-premises purposes as it was only needed for one-time fetching.
