When a well is abandoned, it must be properly plugged and sealed, as set out in Ontario’s Wells Regulation (Regulation 903).
If your well supplies water to multiple residences, a common space, or a local business, you may be required to meet requirements under the Safe Drinking Water Act, or under the Health Protection and Promotion Act (in addition to requirements under the Wells Regulation and the Ontario Water Resources Act).
To find out if these additional legal requirements apply to your well, visit Drinking Water Ontario or contact the Ministry of the Environment at 1-866-793-2588 during regular business hours.
Most well owners don’t have the equipment, materials, or expertise needed to comply with legal requirements. For this reason, you should hire a licensed well contractor when building, repairing, modifying or abandoning your well.
Licensed contractors are required to use licensed well technicians, of the proper class, to conduct or supervise any work being done on your well. Ask to see your contractor’s and technician’s licences, before they begin work on your well.
When your well is constructed or repaired, or when a pump is installed, the person you hire to do the work is required to give you a Well Owners Information Package. This package includes basic information about:
You can request a copy of the Well Owners Information Package from the Wells Help Desk at 1-888-396-WELL (9355) or firstname.lastname@example.org.
You should test your well water at least three times a year. The quality of your well water can change, and changes often aren’t apparent in the taste, smell, or look of your water.
