Why Municipalities Should Help Raise Awareness About Radon

When people think about public health, they often think of clean drinking water, road safety, or vaccination programs. However, there's another invisible health risk affecting thousands of Canadian homes every year: radon gas.

As the second leading cause of lung cancer overall—and the leading cause among non-smokers—radon deserves far more public attention. While homeowners are ultimately responsible for testing their properties, municipalities are uniquely positioned to help educate residents and encourage proactive testing.

The good news? Raising awareness doesn't require new regulations or expensive programs. Even small educational initiatives can make a meaningful difference.

Radon Is a Community Health Issue

Radon is a naturally occurring radioactive gas produced by the breakdown of uranium in soil and rock. It can seep into homes through foundation cracks, sump pits, utility openings, and other gaps in the building envelope.

Because radon is invisible, odourless, and tasteless, the only way to know whether a home has elevated levels is through testing.

According to Health Canada:

• Radon is responsible for more than 3,200 lung cancer deaths in Canada every year.

• It is the leading cause of lung cancer among non-smokers.

• According to Health Canada's latest cross-Canada radon survey, approximately 1 in 5 Canadian homes have radon levels above the Canadian guideline of 200 Bq/m³, although the percentage varies considerably between provinces and communities and based on our 6 years plus experience we noted that 1 in 2 homes have levels too high for comfort.

Every municipality contains homes with varying radon levels. Even neighbouring houses can have dramatically different test results due to differences in soil conditions, construction methods, and ventilation.

Why Municipalities Play an Important Role

Municipal governments are often the first source residents turn to for information about local health, safety, and environmental concerns.

Just as municipalities educate residents about:

• Water conservation

• Flood preparedness

• Fire prevention

• Waste collection

• Extreme weather events

they can also help raise awareness about indoor air quality and radon.

Health Canada specifically encourages municipalities to become leaders in radon education through community outreach, awareness campaigns, testing initiatives, and partnerships with local organizations.

Importantly, this doesn't mean municipalities need to create new bylaws or enforce mandatory testing.

Education Without New Regulations

Many municipalities hesitate because they assume addressing radon requires legislation or significant funding.

In reality, education can be simple and cost-effective.

Municipalities can:

Publish Information on Their Website

A dedicated radon information page can explain:

• What radon is

• Why testing matters

• When to test

• Where residents can purchase test kits or rent a digital device form your local library

• How certified mitigation professionals can help if high levels are found

Promote Radon Action Month

November is recognized across Canada as Radon Action Month, making it an ideal time to share educational content through:

• Municipal websites

• Social media

• Community newsletters

• Recreation centres

• Libraries

Health Canada provides free educational resources that municipalities can adapt for local use.

Include Radon in Welcome Packages

Many municipalities provide information packages to new homeowners.

Adding a simple radon information sheet encourages residents to test early—especially after purchasing a home.

Work With Local Organizations

Municipalities can partner with:

• Public health agencies

• Local libraries

• Community associations

• Environmental organizations

• Certified radon professionals

These partnerships can expand awareness without placing a significant burden on municipal staff.

Canadian Municipalities Are Already Leading the Way

Across Canada, many municipalities have demonstrated that public education can significantly improve awareness.

Examples include:

Winnipeg, Manitoba

The Winnipeg Public Library has partnered on radon awareness initiatives by lending radon detectors to residents, making testing more accessible throughout the community. Demand has demonstrated strong public interest in learning about indoor radon levels.

Regional District of Central Kootenay, British Columbia

Libraries throughout the region have worked with community organizations to distribute radon test kits and educational materials, helping residents better understand their home's radon risk.

Yukon Communities

The Yukon Housing Corporation, working alongside public health partners, has provided free radon test kits while conducting province-wide awareness campaigns that reached even remote communities.

Health Canada also highlights numerous Canadian municipalities that have developed dedicated radon webpages, public education campaigns, community testing initiatives, and awareness resources for residents.

Small Actions Can Save Lives

Public awareness remains one of the biggest barriers to reducing radon exposure.

Many Canadians have heard of radon but have never tested their homes. Others assume newer homes are immune or believe they would notice if radon were present—which isn't the case.

Even a single annual awareness campaign can encourage hundreds of residents to test their homes.

Unlike many health initiatives, radon testing is relatively inexpensive, and effective mitigation systems can dramatically reduce indoor radon levels when necessary.

What This Means for Montreal Communities

The Montreal region includes a wide variety of soil types, home ages, and foundation styles, meaning radon levels can vary significantly from one property to another.

Municipalities across Greater Montreal have an opportunity to help residents make informed decisions by simply sharing reliable information and encouraging long-term radon testing.

By treating radon awareness as part of broader public health and environmental education, municipalities can help protect current residents while promoting healthier homes for future generations.

Test Before You Assume

Whether your home is new or old, large or small, the only way to know your radon level is to test.

If you live in the Montreal area and want professional guidance on radon testing or mitigation, Radon Montreal can help you understand your home's radon risk and recommend the appropriate next steps.

Protecting your family's health starts with a simple test—and community awareness begins with informed local leadership.
