Ontario's NDP and Progressive Conservative leaders will speak at news conferences this morning, a day after the parties took ridings from the ruling Liberals in provincial byelections.
The NDP, led by Andrea Horwath, took two of five seats up for grabs that were all previously held by Liberals.
The Progressive Conservatives, headed by Tim Hudak, earned their first win in Toronto since 1999.
The Liberals held on to two seats, but conceded that the scandal surrounding the costly cancellation of two Ontario gas plants had taken its toll.
"I think people sent us a message loud and clear that they expect better," Deputy Premier Deb Matthews told CBC News on Thursday morning.
