It's at the location your church is physically. If it's a larger church and you have more than one building at a particular site, it would be for that campus site.
If you have 2 or more church building locations, for instance, if you have 2 churches across town from each other, each 'church location' would need their own license.
In the "one license per one church location", what do you mean by location? A single town? City? Province? Thanks.
