The weight of evidence: regulatory toxicology in Canada.
The legislative application of regulatory toxicology in Canada is reviewed, together with the sources of experimental evidence used for action. Examples are given of the critical toxicological information that led to a regulatory decision. Risk numbers have only been used to a limited extent in Canada. Some possibilities for future research are offered.
