The Province of Ontario has 51 first-level administrative divisions, which collectively cover the whole province. With two exceptions,{{#tag:ref|[[Statistics Canada]] treats [[Norfolk County, Ontario|Norfolk County]] and [[Haldimand County]] as one single census division; the [[County of Brant]] and [[Brantford|City of Brantford]] are also treated as one single census division. There would otherwise be 51 census divisions instead of the 49 official ones used by Statistics Canada.|name=Haldimand-Norfolk|group=lower-alpha}} their areas match the 49 [[Census divisions of Canada|census division]]s [[Statistics Canada]] has for Ontario.

The Province has four types of first-level division: single-tier municipalities, [[regional municipality|regional municipalities]], [[county|counties]], and [[district#Canada|district]]s. The first three are types of municipal government but districts are ''not''—they are defined geographic areas (some quite large) used in many contexts. The last three have within them multiple smaller, lower-tier municipalities but the single-tier municipalities do not. Regional municipalities and counties differ primarily in the services that they provide to their residents. (Lower-tier municipalities are generally treated as [[census subdivision]]s by Statistics Canada.)

In some cases, an administrative division may retain its historical name even if it changes government type. For instance, [[Oxford County, Ontario|Oxford County]], [[Haldimand County]], [[Norfolk County, Ontario|Norfolk County]] and [[Prince Edward County, Ontario|Prince Edward County]] are no longer counties: Oxford is a regional municipality and the others are single-tier municipalities. Several administrative divisions in Ontario have significantly changed their borders or have been discontinued entirely. See: [[Historic counties of Ontario]].

A '''single-tier municipality''' is governed by one municipal administration, with neither a county nor regional government above it, nor further municipal subdivisions below it (cf. [[independent city]]).<ref>{{Cite web | url = https://www.ontario.ca/page/list-ontario-municipalities#section-1 | access-date = 14 August 2020 | website = Government of Ontario | title = List of Ontario municipalities }}</ref> Single-tier municipalities are either former regional municipalities or counties whose municipal governments were amalgamated in the 1990s into a single administration. Some single-tier municipalities (e.g., Toronto, Ottawa, Hamilton, Greater Sudbury) were created where a former regional municipality consisted of a single dominant urban centre and its [[suburbs]] or [[satellite town|satellite towns or villages]], while others (e.g., Brant County, Chatham-Kent, Haldimand-Norfolk, Kawartha Lakes, and Prince Edward County) were created from predominantly rural divisions with a collection of distinct communities. 

A single-tier municipality should not be confused with a ''[[List of Ontario separated municipalities|separated municipality]]''; such municipalities are considered as part of their surrounding county for census purposes, but are not ''administratively'' connected to the county.

With the exception of [[Greater Sudbury]], single-tier municipalities that are not considered to be part of a county, regional municipality, or district are found only in [[Southern Ontario]].

'''Regional municipalities''' (or '''regions''') are upper-tier municipalities that generally have more servicing responsibilities than the counties. They generally provide the following services: maintenance and construction of arterial roads in both rural and urban areas, transit, [[police|policing]], [[sanitary sewer|sewer]] and water systems, [[waste disposal]], region-wide [[land use planning]] and development, as well as health and [[social services]]. Regions are typically more urbanized than counties. Regional municipalities are typically an administrative division where an interconnected cluster of urban centres or suburbs forms the majority of the division's area and population, but no single centre is overwhelmingly dominant over the others. Regional municipalities are found only in [[Southern Ontario]].

Although Oxford County and the District Municipality of Muskoka are not called regions, they are defined as regional municipalities under Part 1, Section 1 of the ''Municipal Act, 2001''.<ref>[http://www.e-laws.gov.on.ca/DBLaws/Statutes/English/01m25_e.htm Ontario Municipal Act, 2001].</ref>

Between 1998 and 2001, four regional municipalities that formed their own central city-dominated [[metropolitan areas]] were amalgamated and are now ''single-tier'' municipalities.

* In 1998, the [[Metropolitan Toronto|Municipality of Metropolitan Toronto]] became the amalgamated [[Toronto|City of Toronto]].
* In 2001, the [[Regional Municipality of Ottawa–Carleton]] became the [[Ottawa|City of Ottawa]], the [[Regional Municipality of Hamilton–Wentworth]] became the [[Hamilton, Ontario|City of Hamilton]], and the [[Regional Municipality of Sudbury]] became the [[Greater Sudbury|City of Greater Sudbury]]. At the same time, the [[Regional Municipality of Haldimand–Norfolk]] was split into [[Haldimand County]] and [[Norfolk County, Ontario|Norfolk County]].

'''Counties''' have fewer responsibilities than regions, as the lower-tier municipalities ([[city|cities]], [[town]]s, [[village]]s, [[township (Canada)|townships]]) within the counties typically provide the majority of municipal services to their residents. The responsibilities of county governments are generally limited to the following: maintenance and construction of rural arterial roads, health and social services, and county land use planning. Counties are only found in [[Southern Ontario]] and are also mostly [[Census geographic units of Canada|census divisions]].

Counties may be as large as regional municipalities in population, but their population ''density'' is generally lower (although not as low as in a district.) Counties may include major cities, such as [[London, Ontario|London]], [[Kingston, Ontario|Kingston]] and [[Windsor, Ontario|Windsor]], geographically located within them, but these communities are usually [[List of Ontario separated municipalities|separated municipalities]] that are only considered part of the county for census purposes, but are not ''administratively'' connected to the county. Municipalities are separated when regional or single-tier status is not appropriate for the municipality's population patterns, but their population is still large enough that it may adversely affect the county's ability to provide services to its smaller communities. Also, these cities have not evolved into large urban agglomerations with other communities, as in regions and single-tier cities, but may have small suburbs such as [[Point Edward, Ontario|Point Edward]].

'''Districts''' are regional areas in [[Northern Ontario]] 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 area (Canada)|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 board (Ontario)|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 division in Northern Ontario ever incorporated with a structure like those of counties, regional municipalities, and single-tier municipalities in the southern part of the province. That division was dissolved in 2000, and now constitutes the single-tier municipality of [[Greater Sudbury]].

The term "district" can also refer to second-level districts of the current [[Toronto|City of Toronto]] that make up the [[Amalgamation of Toronto|six former municipalities]] of [[Metropolitan Toronto]] when it was amalgamated in 1998: [[East York]], [[Etobicoke]], [[North York]], [[Scarborough, Ontario|Scarborough]], [[Old Toronto]] and [[York, Ontario|York]].
