It depends on the jurisdiction. In Alberta, they work with the provincial government. They receive training from the provincial government and work on emergency plans that plug into those of the provincial government. In other places, like Manitoba, as I mentioned, the Canadian Red Cross works closely with the communities. Some of them already have robust plans. Others need to brush them up. There's also the whole training aspect. Again, it's a jurisdiction-by-jurisdiction approach.
