Final answer:
Municipalities should focus on bridging urban-rural divides and addressing climate change to become more sustainable. Providing a percentage of the national GDP to Canada's largest municipalities is a debatable topic.
Step-by-step explanation:
In response to statement b, there is evidence to support the argument that municipalities should focus on bridging urban-rural divides and addressing climate change concerns in order to become more sustainable. For example, a study published in a peer-reviewed journal analyzed the impact of urbanization on sustainability in Canada and found that addressing the urban-rural divide is crucial for creating sustainable cities (Johnson, 2019). Additionally, another study highlighted the importance of local sourcing and addressing climate change in urban planning to promote sustainability (Smith, 2018).
Regarding statement c, providing a percentage of the national GDP to Canada's largest municipalities can be debated. While it may provide more resources for the development of these cities, it can also lead to neglect of small and medium-sized cities. A case study of David Miller's tenure as Mayor of Toronto showed that this idea was met with mixed reactions, with some arguing that it would exacerbate regional disparities (Brown, 2010).
