About well contractors

A well contractor is a person, partnership or company in the business of well construction. They must be licensed under the Ontario Water Resources Act.

Specific licensing requirements are in the Wells Regulation. The work a contractor is allowed to do depends on the type of licence held by its well technician employees.

Well contractor and well technician licences expire annually on March 31.

We strongly recommend that you ask well contractors and technicians to provide proof of a valid ministry-issued licence before you retain their services.

You can also confirm licence status by contacting the Wells Help Desk.

Wells directory

This directory lists all well contractors licensed in Ontario. We update the contractor directory periodically.

Listings in the directory should not be taken as advice or a recommendation of any individual contractor.
