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.
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.[1] 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.[2]
The Lower Canada electoral district of Portneuf County was not altered by the Act. The district therefore continued with the same boundaries which had been set by a statute of Lower Canada in 1829:
The County of Portneuf shall be bounded on the north east by the south west boundary line of the Seigniories of Sillery and St. Gabriel, and by a prolongation of the said line, on the south west by the north east boundary line of the Seigniory of Sainte Anne and its augmentation and by a prolongation of the said line, on the north west by the northern boundary of the Province, and on the south east by the River Saint Lawrence; which County so bounded comprises the Seigniories of Gaudarville, Fossambault, Desmaures or Saint Augustin, Guillaume Bonhomme, Neuville or Pointe aux Trembles, Bourg-Louis, Belair and its augmentation, Dauteuil, Jacques Cartier, Barony of Portneuf, Perthuis, Deschambault, Lachevrotiere, La Tesserie, Francheville, Grondines, reste des Grondines, and their augmentations.[3]
1854 to 1867
In 1853, the Parliament of the Province of Canada passed a new electoral map. The boundaries of Nicolet were altered to some extent by the new map, which came into force in the general elections of 1854:
Portneuf was a single-member constituency in the Legislative Assembly.[5][6]
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.[7][8][9]
