A commonly expressed challenge within the Cities Reducing Poverty learning community is how to get to a common agenda for collective impact. This guide by Vibrant Communities Canada will support communities with milestones and resources that can help lay foundations for developing a community-wide common agenda. Vibrant Communities supports cities and local leaders to develop and implement large-scale change initiatives through two learning networks, Cities Reducing Poverty and Cities Deepening Community. A Vibrant Community can be created once the human, social and economic cost of poverty are significantly reduced. Together, these cities/regions aspire to reduce poverty in 100 cities.
