The Green Party earned official party status in 1983 with Schreiner taking over as leader in 2009.
“We started out obviously a couple decades ago as a very small party running very few candidates. Now we’re running a full slate of candidates, a gender-balanced slate of candidates,” Schreiner told Global News during the campaign.
Raised on a farm in Kansas, Schreiner moved to Canada in 1994, when his wife took a job at the University of Toronto.
A few years ago, he made the move from Toronto to Guelph, where he has been working for decades. The city was the ultimate spot to go Green, with clean-tech startups and a city council focused on renewable energy and protecting its water.

The city is ripe for a Green representative, Schreiner told The Canadian Press before the election.
The third time proved to be the charm for Schreiner as this was his third attempt to win the Guelph seat.
In the last election, Schreiner finished third but secured a healthy 19.29 per cent of the vote, ahead of the NDP.
