Well Aware and Well Wise Program Resources for Homeowners
Well Aware
Well Aware was a program of Green Communities Canada that encouraged Ontario’s residential well owners to protect their wells and our common groundwater supplies.
Since 2001, Well Aware has helped more than 3,900 Ontarians to gain confidence in the management of their wells and to protect their family’s drinking water. An additional 217,000 residents have benefited from our Well Aware booklet, “A Guide to Caring for your Well.”
Well Aware Booklet – A Guide to Caring for Your Well
Well Wise
Well Wise is a program administered by the Ontario Ground Water Association to provide water testing for consumers and well contractors.

Ministry of the Environment, Conservation and Parks (MECP) Proposed Regulatory Changes
The Ministry of the Environment, Conservation and Parks is proposing regulatory changes that would allow it and system owners and operating authorities to act quickly to help ensure the province’s drinking water systems and sewage works have the staff needed to continue operations during an emergency. These proposed changes align with temporary measures we enacted during the COVID-19 pandemic and would only be available for use during an emergency that could affect continuity of water related services.
The proposed changes to Ontario’s drinking water and wastewater operator regulations under the Safe Drinking Water Act, 2002 and the Ontario Water Resources Act include:
- Emergency related amendments that aim to help address drinking water and wastewater operator certification issues that may arise during an emergency or its aftermath and provide system owners and operating authorities of drinking water systems and wastewater facilities with temporary staffing options, while continuing to uphold strong environmental protection and ensuring the health and safety of Ontarians and the natural environment.
- Strike and lock-out related amendments that would formalize and clarify the process for owners and operating authorities of drinking water systems and wastewater facilities to request ministry Director’s direction and/or exemption from operator certification requirements during a strike or lock-out.
- Amendments to harmonize the circumstances under which the ministry Director may revoke or suspend a drinking water operator’s certificate or wastewater operator’s licence.
We invite you to view the full proposals on the Environmental Registry and provide your feedback by July 2, 2021:
- Proposed amendments to drinking water operator and water quality analyst certification regulation to address impacts of emergencies (019-3513)
- Proposed amendments to wastewater operator licensing regulation to address impacts of emergencies (019-3515)
MECP staff will continue to support you during this difficult time. Please contact your local ministry district office if you are experiencing operator staffing shortages that may lead to a break in continuity of operations, so that we can discuss potential options to help ensure continued safe operations.
Ontario’s drinking water remains among the best protected in the world. Working with our partners and municipalities, we will continue to ensure our drinking water is held to Ontario’s high safety standards, and that the environment continues to be protected.

Canadian Water Sector Cyber Security Survey
In recognizing the risks that cyber threats create for the water sector, the Canadian Centre for Cyber Security (the Cyber Centre) has engaged Deloitte Canada to conduct a nation-wide study to understand the state of cyber security within some sectors that make up Canada’s critical infrastructure.
If you are one of the key stakeholders in supporting Canada’s water sector, they would like to invite you to participate in this study by responding to a series of questions. The study is intended to gain an understanding of the crucial role you play within the water sector and assess, at a high-level, your cyber security maturity posture. The questionnaire should take approximately 1 hour to complete.
Note: This questionnaire involves cyber security management concepts and terminology. They recommend that someone from your organization who has familiarity with these concepts participate in filling out the survey. For best results, consider involving individuals from your IT and OT teams at the management level to collaborate on your answers.
For additional information about this study or clarifications please read the FAQ section included below or contact them at sector_study_cccs@deloitte.ca.
FAQ
- Who will be conducting the study?
The study will be conducted by Deloitte Canada on behalf of the Canadian Centre for Cyber Security (the Cyber Centre).
- How will the information be collected?
The information will be collected via the Qualtrics survey platform. Access to the information will be restricted to the Deloitte engagement team responsible for conducting the study.
- What will the information be used for?
The information provided will be used to gain an enhanced understanding of the cyber security maturity posture within the Canadian water sector and inform how the Cyber Centre can better engage with the stakeholders to increase stakeholder and collective cyber resilience.
- Who will have access to my information?
Information you share as part of this study will be made available to your organization the Cyber Centre and the Deloitte engagement team exclusively. All outputs shared from surveys will be aggregated and anonymized.

NDMA (N-nitrosodimethylamine)
‘Levels of NDMA in Canadian drinking water are generally very low. There are no industrial or commercial uses for NDMA in Canada. NDMA can be found in both surface water and groundwater sources, but it is found in drinking water primarily from its formation during the treatment process, in particular chloramination. (Health Canada, 2011)’
