On Wednesday morning, Wynne was in Kitchener, where she went on a run with Daiene Vernile, the party’s candidate in the riding of Kitchener Centre.
The Liberal leader then visited a local business, where she spoke to the media.
From Kitchener, Wynne was headed to Brampton to visit MDA Robotics. She was then scheduled to take a trip to Ottawa later in the day.
Wynne told reporters the Liberals have a "fantastic history" in the riding of Ottawa South, where John Fraser, the Liberal incumbent, is running for re-election.
That riding was previously held by Dalton McGuinty, the former premier and Wynne’s predecessor as Liberal leader.
"Dalton McGuinty served that riding so well. John Fraser is a terrific MPP and I'm looking forward to meeting with his team later on," Wynne said.
While it has been clear since last week that an election was going ahead, the campaign did not officially start until today, when the writs were issued.
The election was a given after the New Democrats said they would not be supporting the budget the Liberals had introduced. The Progressive Conservatives had already signalled they would not support it, which meant that the Liberals would not have been able to get their budget passed in the legislature.
