As a result of legislation passed by the Legislature in 2004, election dates are now fixed by formula so that an election is held approximately four years after the previous election, unless the government is defeated by a vote of "no confidence" in the Legislature. Previously, the governing party had considerable flexibility to determine the date of an election anywhere up to five years of being elected. The date of this election was originally presumed to be October 4, 2007;[2] however, the law fixes the date on the first Thursday of October or on any day within seven days thereof if required to accommodate a date of "religious or cultural significance". The date was set as October 10, 2007, to avoid a conflict with the Jewish holiday of Shemini Atzeret, which fell on October 4, 2007.[2]

In the same election, there was a provincial referendum on whether to change from first-past-the-post to mixed member proportional representation, as recommended by the Ontario Citizens' Assembly on Electoral Reform. This measure failed, with 37% of the participating electorate and 5 out of 107 ridings voting for the new system; a 60% supermajority was required province-wide, with at least half the ridings also supporting it by a simple majority.
