Big things are accomplished together. Civility is the glue that binds humans together into disparate, productive groups. So much of human history is about competing for perceived and genuinely scarce resources. The future is however less about scarcity and more about traveling together within a common goal that supports the flourishing of all. Civility, most often nurtured in cities, is essential to developing a metropolitan mindset that moves past the traditional, zero-sum logic of most politics. Building on this mindset, sustainability can be extended across the globe. Recognizing that environmental, economic, or social degradation anywhere is eventually felt everywhere, this chapter concludes with several recommendations to move Canadian cities along the road toward sustainability. These include developing new approaches to housing; establishing at least five Chief Resilience (Sustainability) Officers; catalyzing a new International Mining and Materials Association; expanding the benefits of post-secondary education; enhancing data management systems; empowering Statistics Canada to provide urban sustainability indicators and data connected to local sustainable development goals; and promoting an international outlook within Canadian cities that benefits everyone.
