True, but for the times it still doesn't work, we either involve the police or create a parallel deployed 24/7 'social services/mental health response team' which wouldn't be without its own significant cost.
Equalization payments, just a different line item.
If I recall correctly, the assigned incident commander started out trying to coordinate the response via phone/radio from his home detachment in Perth.

I do wish the County well in its endeavours, but I think when they see the bill and tell the taxpayers what their property taxes will be during at least the initial years, they will spook. Municipalities in Ontario, both those under contract to the OPP or another municipality as well as those with their own department, go through this exercise on a regular basis and the bottom line is usually always the bottom line. A few do seem to be able to overcome it. Deep River comes to mind - they seem to be willing to keep their own PS when municipalities much larger cannot.
According to the Interweb, Cumberland County is about 30,500 people spread over about 4300sqkm. I don't know if Amherst (9,400) is part of the County but I imagine their police service would fancy itself as the nucleus of any new county service. Just going but average police/population numbers, they would be looking at having to fund a minimum of 73 cops, not counting support.
