Andrea Horwath, leader of the Ontario NDP, was the third provincial party leader to visit the Kitchener-Waterloo riding three days.
Horwath says voters in the riding will play an important role in determining the behaviour of the government after the byelection.
She says they will determine "Whether we want to, you know, give that blank cheque back to the Liberals so that they can start behaving arrogant and out of touch again, the way we saw for two other majority governments."
While the byelection in former PC MPP Elizabeth Witmer's riding has not yet officially been called, it has been the destination for party leaders this week.
PC Leader Tim Hudak was in the riding on Wednesday, while Premier Dalton McGuinty visited on Thursday.
Horwath says the premier's job offer to Witmer is his attempt to get a third majority and that he's also trying to lure more opposition members to cross the floor.
"These types of political maneuverings, which are more about the party's political power, are things that make people cynical, I think. People don't like that kind of thing."
Horwath also used her visit to criticize the Progressive Conservatives for what she described as walking away from the budget process.
During her visit Horwath also met with party members and supporters. She is hoping to convince voters the NDP is the best alternative.
Recent polls suggest Horwath has a lot of work to do, with Liberals leading in support ahead of the PCs and the NDP sitting in third place.
But Wilfrid Laurier University political scientist Barry Kay says the riding is up for grabs and the NDP shouldn't be ruled out.
"Polls right now don't mean squat…Historically the NDP sometimes really surprises in byelections."
Kay expects the byelection will be held in October or earlier if the premier has a strike by high school teachers to deal with.
McGuinty must call the byelection within six months.
