Ottawa—Vanier (formerly known as Ottawa East) is a federal electoral district in Ontario, Canada, that has been represented in the House of Commons of Canada since 1935. Previous to that date, it was part of the Ottawa electoral district that returned two members.
The riding generally corresponds to the wards of Beacon Hill-Cyrville, Rideau-Rockcliffe and Rideau-Vanier.
The riding is currently vacant in the House of Commons, due to the death of incumbent MP Mauril Bélanger on August 16, 2016.
The riding, with a large Franco-Ontarian population in Vanier, is one of the most solidly Liberal in the country, having elected Liberals both federally and provincially in every election since its creation. In fact, the previous electoral district which comprises most of the constituency, Russell, had been solidly Liberal since 1887. The riding is home to a large number of civil servants.
