Hiring a Well Contractor

When hiring a well contractor, it is important to ensure that they hold the correct class of license for the type of well they will be working on. All well contractors need to be licensed by the Ontario Ministry of Environment. Be sure to ask to see a copy of their license when you are considering hiring a contractor to work on your well. Make sure the license is current, and covers your class of well (see below).

Service Guide Code

Class 1 – Drilling (and for work on a drilled well)

Class 2 – Boring/Digging (for work on a dug or bored well)

Class 3 – Other Well Construction

Class 4 – Pump Installation and Caps (some plumbers have this license)

A licensed well contractor may hold a combination of one or more classes depending on the classes held by the technicians employed. Thus, someone with classes 2 and 4 would be licensed to work on bored/ dug wells, and also to install pumps and caps. Someone with only a class 4 license can only install pumps and caps and cannot drill wells.

Note that all well contractor licenses expire on March 31 each year.

The Ontario Ministry of Environment has an online list of licensed well contractors.

Well Records

Copies of well records may be obtained from the Ontario Ministry of Environment by calling 1 (888) 396-9355, or may be downloaded at no cost from here.

Some older wells were never registered with the Ministry, and thus records may not be available for every well.
