What is the difference between policy and operational decisions?

In Brown v. British Columbia (Minister of Transportation and Highways), 1994 CanLII 121 (SCC), [1994] 1 S.C.R. 420 at p. 441, Cory J. described the distinction between policy and operational decisions as follows: True policy decisions involve social, political and economic factors. In such decisions, the authority attempts to strike a balance between efficiency and thrift, in the context of planning and predetermining the boundaries of its undertakings and of their actual performance. True policy decisions will usually be dictated by financial, economic, social and political factors or constraints. The operational area is concerned with the practical implementation of the formulated policies; it mainly covers the performance or carrying out of a policy. Operational decisions will usually be made on the basis of administrative direction, expert or professional opinion, technical standards or general standards of reasonableness.
