Not related to the RCMP, but I believe Quebec has been much more prescriptive than the other provinces. I'm not fully aware of the details but they mandated which municipality must maintain their own service and, by default, which must be policed by the SQ. I also believe they laid out some kind of crime benchmark above which smaller departments shall not take the investigative lead. This latter was a problem in Ontario in the days of many small municipal departments who convinced their councils that they were 'full service'. They would hang onto a major investigation until such time public pressure or internal realization forced them to call the OPP. By that time, many investigations were past being recoverable.
