This is page shows results of Canadian federal elections in the city of Calgary, Alberta. Regional profile Calgary is by far the most conservative major city in Canada. This political leaning goes back to the days prior to Alberta's creation as a province, when what was to become Southern Alberta (the Kickinghorse Pass) was selected over Central Alberta (Yellowhead Pass) for the route of the new Canadian Pacific Railway under the auspices of Prime Minister John A. Macdonald. Prior to Alberta joining confederation in 1905, Calgary (and most of what is now Alberta) was represented by the riding of Alberta (Provisional District). From 1904 to 1917, the riding of Calgary represented Calgary. It was then split into two ridings (Calgary East and Calgary West). Like rural Alberta, Calgary was a clean sweep for the main right-wing party of the day in all but one election from 1972 to 2011: Progressive Conservatives through 1988, Reform in 1993 and 1997, the Canadian Alliance in 2000 and Conservative since 2004. The one break with this tradition came in 2000, when PC leader Joe Clark took Calgary Centre. Clark's notability of being a former prime minister and the controversy of Stockwell Day's stances on same-sex marriage being an issue that caused many voters in that riding to turn away from Canadian Alliance candidate Eric Lowther and support Clark instead. With Clark having retired by the next election, Calgary returned to a Conservative sweep from 2004 to 2011. The Conservatives won an outright majority of the votes cast in each Calgary riding during this time, with vote-splitting of the residual minority of the vote among the Liberals, New Democratic Party (NDP) and Greens causing none of the races to be even close. This trend was broken in the November 26, 2012 Calgary Centre by-election, where Liberal Harvey Locke made a formidable showing, capturing nearly 33% of the vote, leaving Conservative Joan Crockatt to capture the riding with just under 37% of the vote. Not only was this well short of a majority, but it was the closest that a centre-left party had come to taking a Calgary riding in memory. The Liberals have increasing support, especially in the centre, and the recent seat re-distributions made Calgary Centre and several other ridings somewhat less safe for the Conservatives. Meanwhile, the NDP has similar overall levels of support as the Liberals, while the Greens are stronger in
