That is one area where the Canadian system for laying out voting districts works far better.
A note about terms
Federal riding, federal electoral district and constituency can all be used interchangeably.
When and why do the boundaries need to change?
According to the Constitution of Canada, federal electoral boundaries must be reviewed every 10 years based on the most recent census to reflect Canada’s ever changing population.
Who decides where the boundaries go?
An independent electoral boundaries commission is created for each province, for a total of 10 commissions. The commissions use demographic data from Statistics Canada and spatial data from Natural Resources Canada to determine if the boundaries need to be changed.
What about the Territories?
Due to their limited population size and the Electoral Boundaries Readjustment Act, the territories are each allocated only one federal electoral district, which is not reviewed.
Who is a part of a federal electoral boundaries commission?
Each commission has three key players: one judge who chairs the commission and two members appointed by the Speaker of the House of Commons (usually academics and researchers).
What criteria are used to determine the new boundaries?
The main criterion is population equality (plus or minus 25%); however, other criteria are also considered by the commission, such as:
communities of interest or identity,
historical patterns of previous boundaries, and
manageable geographic size.
Do citizens get a say?
Of course! Once the commission has prepared proposals of the revised boundaries, there are public hearings held in the affected districts for the public to participate in the
process. Members of the House of Commons can also participate in the hearings.
Does Elections Canada decide where the boundaries go?
Elections Canada plays an impartial support role, such as providing data and assisting with mapping. It then implements the boundary decisions made by the commissions and produces new electoral district maps.
We’re supposed to respect “communities of interest” also, but it doesn’t really happen that way. For example, the City of Laurel, in PG County, is in the Fourth District (under the existing (2011) plan, not the new one.) The Anne Arundel part of Laurel is in the Third (proudly the most gerrymandered district in America), and North Laurel is in the Seventh. (It’s in Howard County.)
Functionally, those are one community — Greater Laurel, usually just considered Laurel. For all practical purposes, they’re the same community. People travel across those county lines all the time. They’re in three different districts.
The Sventh, BTW, is the district where Kimberly Klacik ran.
Except it resulted in Trudeau and his hugely fascist government.
