s. They differ primarily in the services that they provide to their residents.

The varying structures of municipal and regional governments in Ontario can sometimes be confusing, as they result from a variety of approaches to local government, implemented at different times by different provincial governments in specific areas to serve specific needs. Due to the vast disparities among Ontario's different regions, it would be extremely difficult for a provincial government to apply a consistent, unified system across the entire province.

In some cases, as well, a census division may retain its historical name even if it changes government type (e.g. Oxford County

Single-tier municipalities

A single-tier municipality is a census division which is governed by one municipal administration, with neither a county nor regional government above it, nor further municipal subdivisions below it (cf. independent city
Independent city

). A single-tier municipality is either a former regional municipality or a former county, whose municipal governments were amalgamated in the 1990s into a single administration. A single-tier municipality should not be confused with a separated municipality, which is a municipality that is administratively separated from its county, but is not considered a separate census division. With the exception of Greater Sudbury, single-tier municipalities are found only in Southern Ontario

Northern Ontario
Northern Ontario is a region of the Canadian province of Ontario which lies north of Lake Huron , the French River and Lake Nipissing. The region has a land area of 802,000 km2 and constitutes 87% of the land area of Ontario, although it contains only about 6% of the population...

 that do not serve any municipal government purpose. Although districts do still contain incorporated cities, towns and townships, they do not have an upper-tier county or regional municipality level of government, and are largely composed of unorganized areas. Some districts may have District Social Service Administration Boards, which are designed to provide certain social services, but they do not serve a governmental function.

In a district, all services are provided either by the municipalities themselves, by local services boards in some communities within the unorganized areas, or directly by the provincial government. Much of Northern Ontario is sparsely populated, so a county government structure would not be an efficient or cost-effective method of administration.

The former Regional Municipality of Sudbury, created in 1973, was the only census division in Northern Ontario ever incorporated with a structure like those of census divisions in the southern part of the province. That division was dissolved in 2000, and now constitutes the single-tier municipality of Greater Sudbury.
