Ontario’s ban on the use and sale of pesticides for cosmetic (i.e., deemed by the government to be nonessential) purposes took effect on April 22, 2009. The prohibited pesticides are set out in Ontario Regulation 63/09, which lists over 250 pesticide products and 80 pesticide ingredients that are now banned for use and/or sale. The ban also renders inoperative municipal by-laws that previously restricted the cosmetic use of pesticides. The ban would not apply to all uses of pesticides: there are exceptions for, among other things, certain agricultural and forestry uses and the protection of public health and safety.
