2012 Canadian federal electoral redistribution

The federal electoral redistribution of 2012 was a

seats in the House of Commons of Canada increased from 308 to 338. The previous electoral redistribution was in 2003.^[1]

Background and previous attempts at reform

Prior to 2012, the redistribution rules for increasing the number of seats in the House of Commons of Canada was governed by section 51 of the Constitution Act, 1867, as last amended in 1985. As early as 2007, attempts were made to reform the calculation of how that number was determined, as the 1985 formula did not fully take into account the rapid population growth being experienced in the provinces of Alberta, British Columbia and Ontario.^[2]

The revised formula, as originally presented, was estimated to have the following impact:

Allocation of seats in the House of Commons (2010 proposal)^[3]
Province/territory	Current seats	Projected seats after the 2011 census
Province/territory	Current seats	Under the 1985 formula	Under the new formula
British Columbia	36	38	43
Alberta	28	29	33
Saskatchewan	14	14	14
Manitoba	14	14	14
Ontario	106	110	124
Quebec	75	75	75
New Brunswick	10	10	10
Nova Scotia	11	11	11
Prince Edward Island	4	4	4
Newfoundland and Labrador	7	7	7
Yukon	1	1	1
Northwest Territories	1	1	1
Nunavut	1	1	1
Total	308	315	338

Three successive bills were presented by the Government of Canada before its final form was passed by the House of Commons and Senate in 2011.^[4]

Passage of the Fair Representation Act (2011)

The expansion of the House from 308 seats to 338 seats is pursuant to the Fair Representation Act, which came into force on December 16, 2011.^[5] In introducing the bill, the government's stated aims were:^[6]

allocating more seats to better reflect population grown in Ontario, British Columbia, and Alberta;
maintaining the number of seats for slower-growing provinces; and
maintaining the proportional representation of Quebec according to population.

The Act replaced s. 51(1) of the Constitution Act, 1867 with the following formula:^[7]

Divide the estimated population of a province by a determined electoral quotient (initially set at 111,166).
If the number of members determined is less than what a province had in 1985, increase its seat count to that number (the "grandfather clause").
If a province's population was overrepresented in the House of Commons at the completion of the last redistribution process, and would now be under-represented based on the calculations above, it will be given extra seats so that its share of House of Commons seats is proportional to its share of the population (the "representation rule").
Add one seat for each of the territories.

The 1985 minimum has two components:

No province can have fewer MPs than it has senators (the "senatorial clause").^[8]
Otherwise, the calculation determined in 1985 under the Constitution Act, 1985 (Representation) will govern the amount.

Yukon	34,666	n/a				1
Northwest Territories	43,675	n/a				1
Nunavut	33,322	n/a				1
Total	34,482,779					338

The addition of three seats in Quebec marked the first time since the adoption of the 1985 electoral redistribution formula that any province besides Ontario, Alberta and British Columbia gained new seats.

Process of redistribution

The allocation of seats to the provinces and territories was based on rules in the Constitution of Canada as well as population estimates made by Statistics Canada based on the 2006 census (in particular, the allocation is based on an estimate for the population as of July 1, 2011, "based on 2006 Census population counts adjusted for census net undercoverage and incompletely enumerated Indian reserves").^[9]^[10]

A final report was tabled October 2013, with the changes proclaimed to take effect as of the first dissolution of Parliament occurring after May 1, 2014.^[11] The names of some ridings were changed when the Riding Name Change Act, 2014 came into force on June 19, 2014.^[12]

In a report issued in 2014 Elections Canada noted: "While some administrative tasks remained to be done after that point, Elections Canada's role of supporting the federal electoral boundaries commissions, which had worked for up to 18 months in their respective provinces, was complete." The report concluded that "the process for the 2012 redistribution of federal electoral boundaries was a success."^[13]

Alberta^[17]	34	6	Highway corridor west of Calgary to the B.C. border as well as Calgary's northern exurbs. Battle River: Created out of the southern half of Vegreville—Wainwright and the northern half of Crowfoot and a small part of the eastern part of Red Deer. Contains much of rural Central Eastern Alberta. Named for the Battle River which flows through it. Fort Macleod . Named for the Bow River which flows through it. Calgary Centre: This riding shifts eastward, moving the western boundary to 37 St SW and moving the eastern boundary to the Bow River. Calgary Confederation: Created mostly from Calgary Centre-North, except losing the area north of McKnight Blvd and John Laurie Blvd. It also takes in the part of Calgary West north of the Bow River and east of Nose Hill Drive and Stony Trail. Named for Confederation Park. Calgary Forest Lawn: Created mostly from parts of Calgary Northeast and Calgary Southeast and newly annexed territory of the City of Calgary that is now in the riding of Crowfoot.

Riding named for the neighbourhood of Forest Lawn. Calgary Heritage: Created mostly out of Calgary Southwest, except a few small parts of Calgary Southeast caused by adjusting the eastern boundary of the riding to follow Macleod Trail.

Calgary Shepard: This riding is created out of parts of Calgary East and Calgary Southeast as well as newly annexed parts of the city of Calgary now in Crowfoot.
