About CHO:

The Coalition for a Healthy Ottawa is comprised of concerned citizens, health care professionals, scientists, and health and environmental organizations that worked to end the cosmetic use of lawn care pesticides in Ottawa, Canada.

The CHO supports healthy, sustainable landscapes by encouraging organic non-toxic pest management strategies, and seeking a by-law restricting the use of pesticides for lawn care and gardening.

The lack of adequate protection from unwanted exposure to lawn pesticides at the federal and provincial level has fueled a growing surge in municipal pesticide ordinances designed to enhance the protection of public health and the environment.

As of June 2016 the aggregate number of municipal by-laws in Canada totaled 180. Municipalities of all sizes have passed various forms of pesticide by-laws.

The largest was the City of Toronto with a population of 2.6 million while some are as small as Grandview, Alberta with a population of 108. Over to 28 million Canadians, or 85.7% of Canada’s total population (based on the 2011 Census), are benefiting from enhanced protection from unwanted exposure to synthetic lawn and garden pesticides. This figure includes the gold standard province-wide protection provided under Ontario’s Cosmetic Pesticides Ban Act, 2008 and Québec’s Pesticide Management Code, 2003 as well as Provincial Pesticide Acts.in British Columbia, Manitoba, New Brunswick, Newfoundland and Labrador, Nova Scotia and PEI.

History of CHO:

Since 2003, the CHO has been calling for the City of Ottawa to pass a by-law that would restrict the cosmetic use of lawn care pesticides. 

On May 28, 2008, Ottawa City Council overwhelmingly endorsed, with a 17-7 vote,  the Ontario Government's initiative to ban the use and sale of cosmetic pesticides in Ontario (Bill 64 – The Cosmetic Pesticide Ban Act). 

Ottawa Council also recommended that the provincial legislation be amended to permit municipalities to pass bylaws regulating cosmetic pesticide use consistent with the intent of the provincial legislation – to ban the use and sale of cosmetic pesticides. With this Ottawa joins the City of Toronto in requesting this amendment.

On April 22, 2008, Earth Day, the Ontario Government introduced Bill 64 - "The Cosmetic Pesticide Ban Act, 2008" - that would implement a province-wide ban on the cosmetic use and sale of lawn and garden pesticides. 

Ontario’s cosmetic pesticides ban took effect on April 22, 2009. 

Over 250 pesticide products are now banned for sale and more than 95 pesticide ingredients are banned for cosmetic uses (see list here).
The Ministry of Environment's press release can be viewed here.

The Coalition for a Healthy Ottawa thanks and congratulates the government of Ontario for implementing a province-wide ban on the sale and use of cosmetic lawn pesticides.  Ending their use makes good sense!

The time has therefore come for the citizens of Ottawa to respects the basic rights of us all to a healthy environment with clean air, clean water and clean soil.
