Island are historical and have no governments of their own today. However, they remain used as census divisions by Statistics Canada, and by locals as geographic identifiers. Ontario The primary administrative division of Southern Ontario is its 22 counties, which are upper-tier local governments providing limited municipal services to rural and moderately dense areas—within them, there are a variety of lower-tier towns, cities, villages, etc. that provide most municipal services. This contrasts with Northern Ontario's 10 districts, which are geographic divisions but not local governments—although some towns, etc. are within them that are local governments, the low population densities and much larger area have significant impacts on how government is organized and operates. In both Northern and Southern Ontario, urban densities in cities are one of two other local structures: regional municipalities (restructured former counties which are also upper tiers) or single-tier municipalities. Quebec Quebec's counties are more properly called "Regional County Municipalities" (). The province's former counties proper were supplanted in the early 1980s. Alberta A county in Alberta used to be a type of designation in a single-tier municipal system; but this was nominally changed to "municipal district" under the Municipal Government Act, when the County Act was repealed in the mid-1990s. However, at the time the new "municipal districts" were also permitted to retain the usage of county in their official names. As a result, in Alberta, the term county is synonymous with the term municipal district – it is not its own incorporated municipal status that is different from that of a municipal district. As such, Alberta Municipal Affairs provides municipal districts with the opportunity to change to a county in their official names, but some have chosen to hold out with the municipal district title. The vast majority of "municipal districts" in Alberta are named as counties. British Columbia British Columbia has counties for the purposes of its justice system but otherwise they hold no governmental function. For the provision of all other governmental services, the province is divided into regional districts that form the upper tier, which are further subdivided into local municipalities that are partly autonomous, and unincorporated electoral areas that are governed directly by the regional districts. Manitoba The province of Manitoba was divided into counties; however, these counties were abolished in 1890. Jamaica Jamaica is divided into 14 parishes which are grouped together into 3 historic counties: Cornwall, Middlesex, and Surrey.
