Portneuf (Province of Canada electoral district)

Portneuf was an electoral district of the Legislative Assembly of the Parliament of the Province of Canada in Canada East (now Quebec), immediately west of Quebec City. It was created in 1841 and was based on the previous electoral district of the same name for the Legislative Assembly of Lower Canada. It was represented by one member in the Legislative Assembly.

The boundaries for the district were altered to some extent by a redistribution of seats in 1854. The electoral district was abolished in 1867, upon the creation of Canada and the province of Quebec.

1841 to 1854
Portneuf electoral district was to the west of Quebec City (now in the Portneuf Regional County Municipality), running from the northern shore of the Saint Lawrence River to the northern boundary of the Province.

The Union Act, 1840, passed by the British Parliament, merged the two provinces of Lower Canada and Upper Canada into the Province of Canada, with a single Parliament. The separate parliaments of Lower Canada and Upper Canada were abolished. The Union Act provided that the pre-existing electoral boundaries of Lower Canada and Upper Canada would continue to be used in the new Parliament, unless altered by the Union Act itself.

The following were the members of the Legislative Assembly for Portneuf. The party affiliations are based on the biographies of individual members given by the National Assembly of Quebec, as well as votes in the Legislative Assembly. "Party" was a fluid concept, especially during the early years of the Province of Canada.

Abolition
The district was abolished on July 1, 1867, when the British North America Act, 1867 came into force, splitting the Province of Canada into Quebec and Ontario. It was succeeded by electoral districts of the same name and boundaries in the House of Commons of Canada and the Legislative Assembly of Quebec.
