Lamoureux received a law degree from the Université de Montréal in 1996, was called to the bar of Quebec the following year, and worked with the firm Leduc, Leblanc from 1997 to 1998.
The governing Parti Québécois (PQ) had won the seat by a narrow margin in the previous election, and the contest was expected to be close.
[3] Lamoureux focused his campaign on opposition to another referendum on Quebec sovereignty, in the aftermath of the Canadian federalist option's narrow victory in 1995.
[8] The PQ filed an official complaint with Quebec's chief returning officer, and defeated candidate Pierre Bélanger indicated that his party had identified forty confirmed instances of voting irregularities.
[13] In September of the same year, former Liberal Party campaign worker Alberto Berardinucci was fined ten thousand dollars for hiring people to vote several times using false names.
[14] The province's chief electoral officer concluded that the Liberal Party had not orchestrated the vote-buying scheme, and Lamoureux was not personally implicated in the scandal.
