Premier Kathleen Wynne has announced she met with Lieutenant Governor David Onley Friday afternoon to ask him to dissolve the Legislature.
A general election will be held June 12.
The move came after NDP leader Andrea Horwath announced Friday morning her party members would vote against the budget.
For Ottawa-West Nepean MPP Bob Chiarelli, who is also the Liberal energy minister, that announcement meant the gloves came off.
"Tim Hudak is not acceptable to the province of Ontario. He does not represent our values. He represents the values of the Tea Party down in the U.S.," he said.
But Chiarelli didn't reserve his comments for the PC leader alone.
"Andrea Horwath has brought no policies coming forward, she has not any plans whatsoever in terms of what to deliver," he said.
Chiarelli said Liberal party members' campaign offices are already set and ready for an upcoming election.
"Andrea Horwath has been a bit erratic for the past month," Lisa MacLeod, the Progressive Conservative MPP for Nepean Carleton, told CFRA.
"We've known what's been in the budget, so her yesterday not attending the budget lockup and not voting one way or the other for the first confidence motion, I think, sort of signified to me she was relatively unprepared to do her job, despite us knowing what was in the budget," she said.
MacLeod said they are ready for an election.
"This has been a government that I think should have expired about a year ago," she said. "I'm just grateful that budget from yesterday will not see the light of day, will not pass and will not destroy this province further."
The Ontario PCs have been adamant none of their members would support the Liberal budget, regardless of what it contained.
If Wynne forces a vote on the budget she would need the support of her party members as well as 10 non-Liberals in order for it to pass.
