About the Green Party of Ontario

The Green Party of Ontario is independent yet is philosophically aligned with other green parties in Canada and around the world. The GPO is fiscally responsible, socially progressive and environmentally focused, and begins with the basic premise that all life on the planet is interconnected and that humans have a responsibility to protect and preserve the natural world.


The Green Party is made up of people just like you.

We’re small business owners, teachers, doctors, scientists, parents, nurses, workers and professionals, who think the current political system is broken and simply want to make the world a better place.

Party History

The Green Party of Ontario (GPO) became an officially registered political party in 1983, and has been developing in size and sophistication since that time, expanding its membership and rising in the polls. We have increased the number of candidates in successive provincial elections. In the 1999 provincial election, we fielded 58 candidates, and became the fourth largest party in the province. In 2003, we fielded our first nearly-full slate, 102 out of 103 candidates, and received 2.8% of the vote. The 2007 election saw Ontario voters support Green Party values with unprecedented enthusiasm. The GPO, for the first time in history, had a full slate of candidates and garnered over 8% of the vote. We ran a full slate of candidates in both the 2011 and 2014 elections. At present, the GPO is averaging about 9% in the polls.
