I would draw a parallel between SARA and the provincial Species at Risk Act, because the original provincial Species at Risk Act legislation was passed in 1971 or 1973 and was essentially a one-and-a-half-page document that said, Thou shalt not mess with the habitat of endangered species. The new act that came out in 2007 recognized that such a degree of inflexibility was completely unworkable. The new Ontario legislation introduced in 2007 contains provisions for permitting and flexibility for different organizations and has been widely viewed as a vast improvement over the original legislation, which was too rigid.
