What decision did Toronto's leaders make in 1999 that would affect the city for decades?

In 1999, Toronto's leaders made the significant decision to amalgamate the City of Toronto with five surrounding municipalities, creating a single-tier city. This restructuring aimed to streamline governance and improve service delivery but resulted in challenges such as increased bureaucracy and tensions over resource distribution. The decision has had lasting implications on urban planning, public services, and political dynamics in the Greater Toronto Area. Critics argue it diminished local representation and community identity, effects that are still felt today.
