We are thankful to be welcome on these lands in friendship. The lands we are situated on are covered by the Williams Treaties and are the traditional territory of the Mississaugas, a branch of the greater Anishinaabeg Nation, including Algonquin, Ojibway, Odawa and Pottawatomi. These lands remain home to many Indigenous nations and peoples.

We acknowledge this land out of respect for the Indigenous nations who have cared for Turtle Island, also called North America, from before the arrival of settler peoples until this day. Most importantly, we acknowledge that the history of these lands has been tainted by poor treatment and a lack of friendship with the First Nations who call them home.

This history is something we are all affected by because we are all treaty people in Canada. We all have a shared history to reflect on, and each of us is affected by this history in different ways. Our past defines our present, but if we move forward as friends and allies, then it does not have to define our future.

Data summaries

A World Bank initiating report, ‘Building Sustainability in an Urbanizing World’ (2013), provides the starting point for the 101 largest cities. Starting with this list of cities, University of Ontario Institute of Technology researchers projected global urbanization rates and population growth in the world’s 101 largest urban areas to 2100.

This list of cities forms the skeleton to which additional information such as GHG emissions, energy use and mix and local economic development, is now being added. In partnership with other organizations, including the University of Toronto (Civil Engineering), World Bank, Memorial University of Newfoundland (Engineering), World Business Council for Sustainable Development, American Society of Civil Engineers and GDF Suez, city data is regularly iterated and improved.

The Jeffery Boyce Research Program at the University of Ontario Institute of Technology (UOIT) invites all partners, especially the cities themselves, to help with collecting, refining and better understanding information on the world’s largest cities.

Large urban area compendium entries for the World's 101 largest cities are provided here in alphabetical order.
