The association made up of Alberta's 69 counties and municipal districts has rejected a proposed plan to create a provincial police force.
Premier Jason Kenney said late last year that a provincial force would increase service levels in rural areas, decrease overall policing costs and increase local input into policing.
But Rural Municipalities of Alberta says the model proposed by the United Conservative Party government leaves significant gaps in how it would increase service levels in rural areas.
The association says its members have already endorsed a resolution to continue supporting the RCMP in Alberta.
