Changes and trends towards new urban trajectories Introduction The advent of the 21st century saw the rapid urbanization in most of Canadas regions where economic, political and cultural activities have become largely concentrated on a few major cities and emerging urban systems. This paper will analyze how the trends in population growth, stability and decline have become functions of Canadian urban systems. This will look at the population data of the twenty major geographical centers in the country from Stats Can. Moreover, the paper will also concentrate on a particular geographic region Ð²Ð that of Ontario Ð²Ð to ascertain whether certain patterns are emerging. The analysis will be guided by previous literatures on Canadian urban systems.
