Electoral history

Once one of the strongest bastions of PC support in the province (winning 61% of the vote as recently as 1999), and certainly in the Toronto area, Mississauga South provincially has become more and more Liberal in last election cycles, which can be attributed to the demographics of Mississauga South changing, with more socially-liberal-minded young families moving from Toronto into the area, and increasing ethnic populations which are usually Liberal friendly. Prior to Tim Peterson's very narrow upset victory in 2003 (despite a Liberal landslide province-wide, most pundits had predicted PC incumbent Margaret Marland would hold on to the seat), the area had not voted Liberal provincially since Confederation, and the PCs generally held the riding fairly easily (with some exceptions such as the 1987 election, which the PCs won by less than 1000 votes). The riding was one of the most watched in the 2007 election, as it was expected to be one of the closest races in the province. The voters, however, differed from expectations, handing Liberal Charles Sousa a more than 5000-vote victory, as the PC vote fell almost 9% from 2003, which many viewed as a rejection of the automatic installing of floor-crossing Tim Peterson as the PC candidate. The Liberals and particularly the Green Party received the benefit of angry PC voters, seeing a 3% and a 6% rise in voting percentage, respectively.
Voters also rejected the proposal to change Ontario's electoral system from first past the post (FPTP) to mixed member proportional (MMP) in the 2007 electoral reform referendum. The status quo FPTP received 65% of the vote. Given the margin and the parties' and the candidates' positions on MMP (Peterson and the PCs against, Sousa undecided and the Liberals neutral, Cole and the NDP in favour, and Johnson and the Greens in favour), it appears that the vast majority of NDP/Green voters voted in favour of MMP, the vast majority of PC voters for FPTP, and the majority of Liberals for FPTP, with a sizeable minority voting for MMP.
