Nipissing—Timiskaming is a federal electoral district in Ontario, Canada, that has been represented in the Canadian House of Commons since 2004. The riding was formed by the amalgamation of the former Nipissing riding with the southeastern portion of the former Timiskaming—Cochrane riding. The 2011 electoral results in this riding were challenged in court on the grounds that there were "irregularities, fraud or corrupt or illegal practices that affected the result of the election".[3]
Nipissing—Timiskaming consists of:
the Territorial District of Nipissing, excluding:
the Municipality of West Nipissing;
the southeast part of the district;
the Town of Kearney;
in the Territorial District of Parry Sound, the Town of Powassan and the townships of Nipissing and North Himsworth; and
the part of the Territorial District of Timiskaming lying south and east of a line drawn from the eastern limit of the district west along the northern border of the Townships of Harris, Dymond, Hudson, Lundy, Auld and Speight, south along the western border of the townships of Speight, Van Nostrand, Leo and Medina to the southern limit of the district.
Despite the fact that 99% of this riding stays the same after the 2012 redistribution, based on the results of the 2011 election — in which Aspin defeated Rota by a margin of just 18 votes — the minor boundary changes were enough to make the seat a notional Liberal riding. The riding loses two Conservative voting areas in the north (Hudson Township and Harris Township) while gaining the Nipissing 10 Indian Reserve, where the Tories finished third.
