Guidance for Newcomers to Canada about Drinking Water and Wastewater Operator Certification in Ontario

We warmly welcome newcomers to Canada interested in a career in drinking water and wastewater operations. Our aim is to provide you with the information and services needed to navigate your career journey effectively. As you pursue your career and residency goals, it’s important to clarify that in Ontario, an Operator-in-Training (OIT) certificate or licence, while a critical first step, is not considered a certificate of qualification in a skilled trade for applications for permanent residency.

For further details about obtaining your certificate or licence for the first time, please visit the ‘Operator’ section of our website.
