The problem with Ottawa is that, as the National capital, it is cursed by being administered by no less than four levels of government (i.e. federal, provincial, municipal, and, worst of all, the National Capital Commission), three of which have their own law enforcement agencies.

The solution is quite simple:  turn Ottawa-Gatineau into a federal district, similar to Washington DC, Canberra in Australia or Brasilia in Brazil.

One district to rule them all, One district to find them,
One district to bring them all and in the darkness bind them
On Parliament Hill where the shadows lie
