One of the inspirations of this plan is the methodology developed by Ouranos (2010), which structures the development of a municipal plan for adaptation to climate change in five stages: the assessment of the impacts of the current climate, defining the potential impacts of climate change and analyze vulnerabilities, carry out a risk assessment, find and prioritize options to manage risks and, ultimately, produce and implement the adaptation plan. This has however been adjusted to include advances in knowledge since the publication of the guide, the approach of this plan aimed to increase the resilience of the community in the face of the current and future climate by establishing a list of adaptation actions to be undertaken, particularly in the areas of public health and municipal infrastructure. Although actions with co-benefits that would also contribute to climate change mitigation are a plus, priority was given to initiatives promoting adaptation. Each relevant adaptation option identified in the scientific literature and the plans of other municipalities in the region was thus analyzed based on a vulnerability index developed by the City to facilitate decision-making and implementation. Applied at the scale of dissemination areas, this index integrates sensitivity and adaptive capacity, the latter being calculated, among other things, from the costs and effectiveness of the measure. The final recommendations are based on the coping strategies that best reduce vulnerability.
Further to reports published by the Federation of Canadian Municipalities (FCM) and the Union des municipalités du Québec (UMQ) on the issue of climate change and municipalities, the City of Magog, in southern Quebec, adopted in 2021 its first Climate Change Adaptation Plan. To build this plan, the City referred to Élaborer un plan d’adaptation aux changements climatiques : Guide destiné au milieu municipal québécois (a French-language guide to assist Quebec municipalities in developing a Climate Change Adaptation Plan), published by Ouranos, and worked with numerous stakeholders, including citizens and several local environment and conservation organizations. The plan it produced outlines the main actions needed to increase the resilience of the municipality and its population regarding the impacts of climate change.
