Green Party of Ontario Leader Mike Schreiner will table his first ever private member's bill Wednesday. In it, he asks the province to protect a drinking water source for Guelph, Wellington county and Waterloo region. It's the first bill introduced by the party in the provincial legislature. "For decades the people of Guelph have shown the province how to responsibly use water and what it means to defend water against private interests. Now, climate change and sprawl are putting even more strain on our water supply, so we must take action to protect what's left," Schreiner said in a release prior to tabling the bill Wednesday.
