Sample Bylaw

A Possible Draft Pesticide Bylaw for Calgary

In addition to the Bylaw below, The Coalition for a Healthy Calgary is proposing that the City of Calgary's regulations regarding weed control be brought into line with the Province of Alberta's regulations. Years ago, the City of Calgary took all the nuisance and noxious weeds on the Province of Alberta's list and made them noxious weeds on the Calgary weed list, including dandelions. Changing this means amending City of Calgary, Community Standards Bylaw 5M2004, Section 45, b & c, to align with provincial weed classifications under the Alberta Weed Control Act.

The Possible Draft Pesticide Bylaw for Calgary is based on the Toronto, Ontario bylaw passed in 2003 and amended in 2004. This bylaw would allow for using chemical pesticides on ragweed, an allergy-causing weed if less-toxic alternatives were not effective. This bylaw could also allow for chemical pesticides to be used on invasive species of plants if less-toxic alternatives were not effective.

This bylaw could be phased in, so people have time to adjust. For example, once Toronto implemented it’s pesticide bylaw, bylaw officers issued warnings for two years and only started fining unnecessary pesticide users after three years. Some Municipalities, like Halifax, have implemented the bylaw more quickly for schools, parks, playgrounds, day cares, senior citizen’s residences, universities, churches and hospital grounds.
