To go back to the O/P's question, are you looking for a detachment boundary map, or a map so detailed that is shows the OPP patrol zones within each detachment's patrol areas? For example, Port Credit detachment's territory is subdivided into zones, meaning specific sections of highways like the QEW, 403 and 401 are divided into geographic sections, a.k.a. "zones". I've never seen a map posted online taken to that level of detail.
