At-large
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.
Canada
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:
North Bay, Ontario (all councillors at-large)
Portage la Prairie, Manitoba (all councillors at-large)
St. Albert, Alberta (all councillors at-large)
