About Gasbusters
Despite its widespread use and simple design, the two-stroke (or two-cycle) gas-powered leaf blower engine, invented nearly 150 years ago, is notorious for its inefficiency and environmental impact.
The engine does not have an independent lubrication system, requiring gasoline to be mixed directly with oil. Approximately 30% of the gasoline/oil fuel in a 2-cycle engine used in leaf blowers is emitted unburned through the exhaust. This exhaust releases an aerosol containing various air pollutants that we breathe.
GASBUSTERS is an initiative supported by over 600 Toronto residents and community associations, aimed at promoting the transition from gas-powered leaf blowers to quieter, emission-free alternatives.
Our stance is based on scientific evidence highlighting health risks and the potential harm to your health.
Studies support GASBUSTERS' concerns about harmful noise and the toxic emissions from these machines.

Why Banning Gas-Powered Leaf Blowers Matters
Gas leaf blowers and other 2 cycle garden equipment disrupt neighbourhood tranquility and pose various health risks.
Inefficient 2-cycle gas-powered leaf blowers are unusually loud and can cause hearing damage. The noise from the commercial gasoline powered leaf blower is up to 115 decibels of frequency sound. Overextended time period, the noise exposure above 75 decibels can result in hearing loss.
The Centers for Disease Control and Prevention (CDC) indicates that noise-induced hearing loss is the only type of hearing loss that is fully preventable. Gas-powered leaf blowers generate noise levels that can result in tinnitus for operators. Chronic noise exposure may also elevate the risk of heart attacks and strokes due to its impact on cardiovascular health. Studies have linked untreated hearing loss to increased anxiety, depression, loneliness, stress and dementia. Mitigating noise-induced hearing loss is both straightforward and cost-effective. If the sound intensity sounds loud, it’s too loud and poses a risk to auditory health.
3. Gas-leaf blowers (GLBs) emit toxic carcinogens into the air, causing respiratory issues. For instance, the concentration of the chemical Benzene from the GLB exhaust is nearly one hundred times higher than that from automobiles. California research going back 30 years identifies leaf blower emission when ingested in the lungs will compromise people with underlying lung conditions. If you can smell gasoline fumes you have ingested which compromises a person’s ability to fight off the illness.
4. Leaf blowers generate fine particulates in airborne dust, including street dust containing asbestos from brake linings, carbon black from tire wear, and other debris. The clouds of toxic dust participles can stay airborne for days for all to breath.
5. Leaf blowers’ forceful gusts of wind damage lawns, gardens and beneficial insects and animals including pollinators.
6. Leaf blowers contribute to water pollution in neighbourhoods through emissions, fuel spills, grass clippings, and clogging storm sewers, which pollute local waterways.
7. Gas leaf blower emissions contribute to greenhouse gases and exacerbate climate change.
8. Toronto City Council aims to cut greenhouse gas emissions by 2040, 10 years earlier than planned. Their target is among the most ambitious in North America. Banning gas-powered leaf blowers and switching to alternatives will help achieve the TRANSFORMTO strategy for phasing out fossil gas in City-owned facilities by 2040.
Built broad public support for banning the use of gas leaf blowers.
Educate the public about the health risks and environmental hazards associated with gas leaf blowers and related garden equipment.
Spoke at the Infrastructure & Environment Committee about pollution and the significant impact from gas leaf blowers on both our environment and the quality of life in our communities.
Spoke about the harmful noise from gas leaf blowers at the Noise Bylaw Review, Municipal Licensing & Standards, and the Economic & Community Development Committee.
Monitored and responded to City of Toronto initiatives that can help achieve our goal of banning the use of gas leaf blowers and related garden equipment.
Encouraged Councillors to pass a by-law banning the use of two-stroke equipment, including gas-powered leaf blowers, so the landscape industry has time to transition.
What We’ve Done
What We Intend To Do
Steps to Pursue in 2025
GASBUSTERS to encourage City Councillors to prioritize legislation that bans the use of two -stroke, gas- powered leaf blowers.
Though a ban is not certain, City Council has taken steps to pursue a ban on gas-powered leaf blowers. The decision to transition to zero emissions outdoor power equipment was approved by City Council in July 2023 (2023.IE5.1 ), where Council expressed support for the ban “as a precaution against any adverse impacts to human health and climate. In order to ensure a feasible approach to transitioning towards alternative equipment and practices, the City is engaging residents, businesses and industry stakeholders on the implementation of a ban. City Staff were instructed to carry out consultations and determine the resources needed to develop and enforce the ban and submit a report to the Infrastructure and Environment Committee in 2024. “
The core objective of Toronto Public Health is to reduce health inequities and improve the health status of Torontonians. The Toronto Medical Officer could be a voice to champion the negative health consequences of noise pollution and harmful pollutants from gas-powered leaf blowers.
The carcinogenic benzene fumes, formaldehyde and fine particulate matter are linked to serious health problems such as respiratory and cardiovascular diseases. The vapours can cause leukemia and cancer in blood forming organs.
Recognizing how these pollutants contribute to broader environmental issues affecting air quality and public health, Toronto Public Health could recommend stiff restrictions to discourage their use.
In 2001 (24 years ago), Dr Sheela Basrur, Toronto Medical Officer, submitted a report to prohibit gas-powered leaf blowers in Toronto to Council. It was not passed at City Council.
“Excessive noise exposure can lead to hearing loss, cardiovascular, cognitive, sleep and mental health outcomes.”
(Noise Action Plan, Toronto Board of Health, March 18, 2025)
Gasbusters aims to persuade Dr Na-Koshie Lamptey, Deputy Medical Officer at Toronto Public Health, to address this issue.

What You Can Do
Join Gasbusters
As awareness of the health risks associated with gas-powered leaf blowers increases, GASBUSTERS relies on your support to grow its membership and strengthen its collective voice.
Contact your municipal councillor. Send them an email to express your supporting the transition to a ban.
Copy : mayor_chow@toronto.ca asking her to approve passing a bylaw.
Engage with your community, connect with your neighbour.
Educate people. Distribute our 2 page handout (Resources)
Consider telling the people who matter to you about it.
Join our campaign to ban the use of gas-powered leaf blowers and garden equipment.
We’ll keep you informed of the latest developments and how to make your opinion heard at City Hall.
As a resident of Toronto your voice is powerful. You elect councillors to represent your interests. We encourage all constituents to use their voice to influence local policies and improve the quality of life in your neighbourhood.
Change how you care for your lawn
Reconsider your landscaping choices. Clearing the fallen leaves with a leaf blower sweeps away prime habitat for a lot of creatures and also disrupts the habitats for critical pollinating species such as bees, butterflies and moths, as well as other critters including amphibians and small mammals like chipmunks.
When you minimize your lawn, add more garden beds and let the leaves lie where they fall, there’s a lot less need to use leaf blowers.
Talk to your landscaper or property manager about changing landscaping methods
Hire lawn care services that use battery-powered lawn care equipment. If you are renting, talk to your property manager about switching from loud gas leaf blowers.
Tell your Councillor you want gas-powered leaf blowers banned

Monty McDonald P. Eng, MBA (retired)
Monty , retired Chemical Engineer, lives in Bayview Village. He had extensive experience in the Petrochemical Industry when many chemicals used and produced were carcinogens. This necessitated complete and costly reengineering of manufacturing and distribution operations to ensure plant workers and the public were not exposed to them. This influenced his role as Chair of The Bayview Village Environment Committee, partnering with Canadian Tire to encourage residents to exchange highly polluting Two Cycle lawn and garden equipment for clean running alternatives. He also teamed up with early Gasbusters in 2019 to encourage Councillor Shelley Carroll to present her first Member’s Motion to ban gas-powered leaf blowers in Toronto..
Monty founded a not-for-profit company of volunteers (Vimy Oaks Legacy) repatriating descendant trees from acorns gathered in WW1 at Vimy Ridge by a Canadian soldier and planted on his Scarborough farm. In 2018 one hundred and twenty trees were planted back on the Vimy Battlefield in a Centennial Park beside the Canadian Memorial.
