Premier Dalton McGuinty will be at the Toronto Board of Trade for breakfast then will head to Mississauga to tour a manufacturing plant.
Progressive Conservative Leader Tim Hudak will be in Mississauga, then heads to Kitchener.
The NDP's Andrea Horwath is to make an announcement at the Rogers Centre Skybox.
The tone between the Liberals and Conservatives hasn't changed.
McGuinty continues to call on Hudak to apologize for referring to new Canadian citizens as foreigners, something the premier brands as xenophobic.
But Hudak is refusing to say sorry after slamming a Liberal tax credit proposal as an "affirmative action program to hire foreign workers."
Hudak's also reaffirmed his promise to slash waste from the health care system and that has some critics predicting massive spending cuts.
But he says his own daughter's health troubles have cemented his commitment to public health care and won't reduce services.
