"We base concern on the conclusions of the International Agency for Research on Cancer (IARC) that state that some substances used in pesticides are classified as known, probable or possible carcinogens. In some cases, evidence linking pesticides and cancer will not be scientifically definitive, but it may be suggestive and growing." Canadian Cancer Society

October 19, 2007 - Dundas News.

The Canadian Cancer Society congratulates the City of Hamilton for passing a bylaw restricting the use of ornamental pesticides. Hamilton has now joined neighbouring municipalities including Toronto, Oakville, Guelph and London as a leader in health promotion and environmental protection by adopting a pesticide by-law with residents' health and environment in mind.

The society is concerned about the effects of using potentially cancer-causing substances to enhance the appearance of gardens, lawns, parks and recreational facilities.

We base this concern on the International Agency for Research on Cancer, which states that some substances used in pesticides are classified as known, probable or possible carcinogens.

Since the ornamental use of pesticides has no countervailing health benefit and has the potential to cause harm, the Society supports a complete ban on the use of pesticides on lawns and gardens, especially when safer alternatives exist.

Upon evaluation of the bylaw, the society encourages the City of Hamilton to further protect the health of its residents by removing the "infestation clause" and section 3.2.2 (e) regarding marking of athletic fields from the by-law.

1. Removal of the "infestation clause" [including 3.2.2 (a), (c), (d), Schedule C and Schedule D, iv.]

The "infestation clause" was a major point of debate for Toronto council, prompting a full year of discussions over what exactly constitutes an infestation.

Our view is that the infestation clause is not needed because the Hamilton bylaw already has an exemption any time pests are a "Health Hazard" (see Schedule D, vii). In other words, if homeowners have rats, mice, termites, poison ivy, cockroaches - or any other health threat from a plant or animal - they can use a pesticide. In fact, the remaining conditions outlined in Schedule D (i.e. General Pesticide Applications Outside the Scope of the ByLaw) are sufficient for ensuring the protection of human health and the environment, as adjudicated by a qualified Public Health official.

By removing both the infestation clause and Schedule C, the City of Hamilton will eliminate possible abuse of the by-law and make it easy for inspectors to enforce. In its current state the infestation clause will require inspectors to count dandelions.

Not removing the clause could also destroy the entire intention of the Hamilton bylaw - to allow pesticide use only where it's necessary to protect public health.

2. Removal of 3.2.2 (e) regarding marking of athletic fields

Pesticides should not be used where children play. Using pesticides to mark fields for football, soccer, baseball, etc. is unnecessary, especially since it is known that some substances used in pesticides are classified as known, probable or possible carcinogens and have been linked to other ill-health outcomes.

Healthier alternatives exist and the Society encourages the City of Hamilton to explore and utilize these alternatives.

It is worth noting that the City of Peterborough - which passed a model pesticide bylaw in 2005 - has no infestation clause and has minimal exemptions allowing for pesticide use. Peterborough's bylaw is simple for residents to understand and is easy to enforce. The Canadian Cancer Society encourages other municipalities to model their bylaw to Peterborough's great example.

Once again, we would like to congratulate your council on showing strong leadership for the citizens of Hamilton.

Hamilton is the 27th municipality across Ontario to adopt a by-law restricting the use of ornamental pesticides.

Enacting healthy public policy such as this by-law protects residents from exposure to toxic chemicals and contributes to a healthier Hamilton community for all to enjoy.
