Calgary Heritage is a federal electoral district in Alberta, Canada, that has been represented in the House of Commons of Canada since 2015. Calgary Heritage was created by the 2012 federal electoral boundaries redistribution and was legally defined in the 2013 representation order. It came into effect upon the calling of the 2015 Canadian federal election, which was held that 19 October. It is essentially a reconfigured version of Calgary Southwest, the former riding of Stephen Harper, who served as the Prime Minister of Canada from 2006 to 2015. Territory from the former Calgary Southwest comprises 99% of the new riding, while territory from Calgary Southeast makes up 1%.
