The Royal Society of Canada, the country鈥檚 premier scientific body, has
called for all crops produced by genetic modification to undergo rigorous safety
testing. In a report commissioned by the Canadian government, but highly
critical of its approach to regulating GM foods, the society says that the
principle of 鈥渟ubstantial equivalence鈥濃�攖he assumption that GM foods are
substantially the same as other foods鈥攊s scientifically unsound. Britain
and the US also apply this principle. Canada is the world鈥檚 third-largest
producer of GM crops.
