The 42nd Ontario general election is tentatively scheduled to be held on October 4, 2018. Under amendments passed by the Legislative Assembly of Ontario in 2004, Ontario elections are now held on the first Thursday of October in the fourth calendar year, unless the Assembly is dissolved earlier by the Lieutenant Governor of Ontario due to a motion of no confidence. Such a dissolution is unlikely as the current government has a majority.
Like the previous Representation Act tabled in 2005, 11 ridings have been preserved for Northern Ontario, while the rest of the province will be divided into 111 electoral districts which follow the 2013 Representation Order. Upon the bill receiving Royal Assent, the Assembly's seat count will from 107 to 122. The changes would take place provided the current Assembly does not dissolve before November 30, 2016.
