@morganastra idk the specifics of the BA municipalities, but history bears out that amalgamation isn't effective or productive, amounting to same mentality of business merger & "syngeries" & "cost savings" unrealized: https://en.wikipedia.org/wiki/Amalgamation_of_Toronto#1998_amalgamation
i offer that the Minnesota Fiscal Disparities Act of 1971 would be a better model for inter-municipal co-operation & giving teeth to the 7-county Metropolitan Council of the Twin Cities
@morganastra also, a note on Québec's attempt to amalgamate Île-de-Montréal in 2002, followed by several former municipalities voting to de-amalgamate shortly thereafter
