On Monday, the governing Liberals introduced a pair of supply motions, which essentially allow the minority government to pay its bills.
The supply motions are matters of confidence, which could have toppled the government if enough opposition members voted against them.
The Progressive Conservatives have long been pushing for an election and wanted the New Democrats to help them bring down the government.
But the New Democrats said it was irresponsible to vote against supply motions.
NDP Leader Andrea Horwath said that had the supply motions been voted down, Elections Ontario would have been unable to spend money to run an election campaign that would have been triggered.
The coming budget will be the real test of whether the government can survive another period without an election, as the minority Liberals will need one of the two opposition parties to support them.
For the past two years, the New Democrats have won concessions from the government in exchange for their support during the budget process.
