Population projections, or estimates, were released by Ontario's Ministry of Finance (MOF) in the spring of 2010. The base population for the projections is taken from Statistics Canada's July 1, 2009 preliminary July 1, 2009 postcensal population estimates.
The projections are an estimate of population growth for the province that help Ontario ministries, municipalities and other users plan and provide future services. Projections are based on assumptions about births, deaths and immigration and relocation over the projection time frame. The assumptions used by MOF are based on the study of past trends, as well as expectations for the future. Projections at the county or district level are for the “most likely to occur" scenario.
