The Ontario Liberal Party is one of the province's major political parties, having governed Ontario during several periods including 2003-2018. Historically one of the two dominant parties alternating in power, the Liberals were reduced to third-party status after the 2018 election. The party generally positions itself centre to centre-left on the political spectrum. As a third party (as of 2024), the Liberals work to rebuild support and present alternative policies. Ontario's provincial politics significantly affect municipalities, and understanding all major parties' positions helps municipal leaders navigate the political landscape and prepare for potential future government changes.
