At-large is a designation for members of a governing body who are elected or appointed to represent the whole membership of the body (for example, a city, state or province, nation, club or association), rather than a subset of that membership. At-large voting is in contrast to voting by electoral districts.
If an at-large election is called to choose a single candidate, a single-winner voting system must necessarily be used. If a group of seats must be covered, many electoral systems can be possible, from proportional representation methods (such as PR-STV) to block voting.
A number of municipalities in Canada elect part or all of their city councils at-large. Although this form of municipal election is most common in small towns due to the difficulty of dividing the municipality into wards, several larger cities use an at-large system as well:
At the federal level, Canada's three territories, Yukon, Nunavut and the Northwest Territories are each represented in the Parliament of Canada by one at-large Member of Parliament and one at-large Senator. However, all Canadian provinces, regardless of size, are divided into multiple electoral districts.
In Israel, elections for the Knesset (the national parliament) are conducted on an at-large basis by proportional representation from party lists. Election of municipal and town (but not regional) councils is also done on an at-large basis by proportional representation from party lists.
