Welcome to Careers at OCWA!

OCWA is an agency of the Government of Ontario, reporting to the Ministry of the Environment and Climate Change. Our employees are part of the Ontario Public Service. As the largest provider of water and wastewater services in Canada, we manage over 800 facilities from small well systems and lagoons to large water and wastewater treatment plants. Our clients come in all shapes and sizes, from municipalities serving hundreds of thousands of people to small water systems serving less than a hundred homes to private systems. Together we produce over 800 million litres of drinking water and treat more than 1.1 billion litres of wastewater every day!

What we do makes a difference

Our people at OCWA make it look effortless. It isn’t. A lot of work goes into taking water from its source — a lake or an underground well — and making it safe to drink.

Water is a finite resource. Good source water is becoming harder to find. And we have to ensure that there’s enough water flowing to meet the growing thirst of Ontario communities. We start by testing water at the source to see what’s in it. All the water from lakes and wells must be treated to be safe. Our job is to make sure that every drop of source water is clean and clear before it arrives in anyone’s home — no matter which tap we turn on.
