Municipal Implications

Climate change affects Ontario communities in many ways, but one of its most obvious impacts is the increase in storm and shoreline flooding. Adapting to more frequent extreme weather events such as flooding will be key to ensuring long-term social and economic stability across the province.

Flooding is a priority issue for many Ontario municipalities, and particularly for those on shorelines.  AMO is in the process of preparing an advocacy paper to be released soon on municipal strategies to better respond and adapt to flooding. Key needs include:
  • greater clarity on jurisdictional responsibility for the costs of flooding;
  • adequate and sustained funding by the provincial and federal governments around both flood recovery and adaptation projectsl; and,
  • a coordinated approach to update flood mapping so municipalities can accurately identify flood hazard areas and reduce risk.
Municipal governments also provide residents with stormwater management and treatment services. AMO has long called for funding to improve and expand flood protection and storm water management infrastructure given the increase in the frequency and intensity of storms. This would be prohibitively costly for municipalities to undertake on their own. Municipal budgets are already under immense strain due to the impact of the COVID-19 pandemic.

In the context of COVID-19, AMO encourages Ontario and Canada to provide additional funding to improve municipal storm water management and for flooding control infrastructure including green infrastructure and wetlands as part of its economic recovery efforts. This funding could act as an economic stimulus. 


Although municipal governments often take up additional environmental protection roles beyond those required by regulations, they rely on the federal and provincial governments for key investments to safeguard Ontarians.

In response to the Flood Advisors Report, which followed the devastating floods of 2019, the Province released its Flooding Strategy earlier this year. AMO welcomes the priorities and goals laid out in this report and looks forward to working with the provincial government to put this strategy into action.

AMO hopes that the Province works strategically and collaboratively with municipal govenments  on flood preparedness and mitigation. A partnership approach amongst all three orders of government is essential to ensure that municipal governments have the resources they need to keep their residents safe in the immediate term, and to better adapt to increased extreme weather events both now and into the future.
