How people elect parliaments


Legislative Assembly

Specific Elections: 2014 – 2018


Ontario has a unicameral Legislative Assembly, an assembly of 124 members following the 2018 election.

As of 2018 the province bases the boundaries of the Legislative Assembly electoral divisions (known formally as ‘districts’ and colloquially as ‘ridings’) on those used for the province for the elections for the national House of Commons, with the exception of two ridings in the sparsely populated north of the province, where federal divisions are subdivided. For information on the national practices for regular reviews of the division boundaries see the entry on the House of Commons.

Terms of the Legislative Assembly are nominally fixed at four years. However there remains a capacity for the Premier to advise the Lieutenant Governor to dissolve the Assembly early and call an election.

All the members of the Legislative Assembly are directly elected in single member divisions (termed ‘ridings’) by the plurality voting method.

Commentary and analysis



[recent redistricting]

Inequality in the effective influence of voters caused by variations in House of Commons riding enrolments has been substantial in recent elections, with the most recent standard deviation of variations compared to the mean enrolment being X.X% in 20xx.
