We can answer that question with a categorical No. Over and over, those pushing pesticides will defend them by claiming that the federal registration is a guarantee of safety. Pesticide regulation is all about balancing the risks of their use with their economic benefit. All too often, chemicals will stay in use because government decides that the economic benefit outweighs the human health risk. Once a chemical is registered for use in Canada, it is extremely difficult to get it banned.
Governments are slow to take action.
Unfortunately, governments act as though chemicals have constitutional rights and must be presumed innocent until proven guilty. When the environment and human health are at stake, chemicals should be presumed guilty until proven innocent. Of course, each pesticides is different and can provoke very different concerns. For instance, the widely used fumigant methyl bromide, in addition to being extremely poisonous and responsible for many deaths due to occupational exposure, is responsible for between five and ten percent of worldwide ozone depletion. Banning methyl bromide is essential if we are to protect the ozone layer which protects all living things from the sun's harmful rays.
