The pdf is good for knowing where all the detachments are, but I think what he's wanting to understand is what the zones are for each of his travels and where they're all mapped out for coverage. The problem is, the wiki isn't fully updated The detachments may be listed for places like the GTA etc., but the Zones aren't actually listed.
Ontario Provincial Police (ON) - The RadioReference Wiki
Central Region, only detachments are listed with there Ops channels, same with Northwest Region, Eastern region has only a few more zones to be mapped out along with some of the others...
I would think most OPP zones is formatted as such, Cities, Towns, Regional Municipalities, Townships, Highways (400/401/407/416/417 etc..) Etc.. Yes some may share or cross over into other areas depending on response needed otherwise, they would mostly be dispatched to there respective zones...
Listen to where the following usually get dispatched to and map it out. Like I said, it takes time, but it can be done.
1XX Zone 1 units
2XX Zone 2 units
3XX Zone 3 units
4XX Zone 4 units
5XX Zone 5 units
6XX Zone 6 units
7XX First Nation units
