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 Megantick electoral district of Lower Canada was not altered by the Act, and therefore continued with the same boundaries which had been set by a statute of Lower Canada in 1829:
The County of Megantick shall be bounded on the north west by the south lines of the augmentation of Lotbinière, and part of Saint Jean d'Eschaillons to the River Becancour, being the south east boundary lines of the County of Lotbinière as before described, on the north east in part by the west lateral lines and rear lines of the seigniories of Sainte Croix and Saint Giles, on the west by the east bounds of the township of Stanford, then easterly along the north west bounds of the township of Arthabaska to its intersection with the north west outline of the township of Halifax, thence south westerly along the north west bounds of Halifax, to the northern angle of Chester, thence south easterly along the north east bounds of the townships of Chester, to the most easterly angle of the said township, thence north easterly along the north west outline of the township of Wolfstown, to the most northerly angle of the said township, thence south easterly along the north east boundary line of the said township, to the easterly angle of the same, thence south easterly to the River Chaudière or Lake Megantick; which County so bounded, comprehends the townships of Somerset, Nelson, Halifax, Inverness, Ireland, Wolfston, Leeds, Thetford, Broughton, Colraine, Tring, Shenley, Oulney, Winslow, Dorset and Gayhurst.[3]
The following were the members of the Legislative Assembly from Megantick. "Party" was a fluid concept, especially during the early years of the Province of Canada. 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.[5][6][7]
