Dichlorodiphenyltrichloroethane

Dichlorodiphenyltrichloroethane was first registered as a pesticide under the Pest Control Products Act (PCPA) in the 1940s, and although it was never manufactured in Canada, it was widely used in pest control products until the 1960s. In response to increasing environmental and safety concerns, most uses of DDT in Canada were phased out by the mid-1970s. Registration of all uses of DDT was discontinued in 1985, with the understanding that existing stocks would be sold, used or disposed of by December 31, 1990. The sale or use of DDT in Canada today constitutes a violation of the PCPA.
