Nimonik is a new on-line service for keeping track of changes in environmental laws across Canada. Beginners can use it to get a general sense of the environmental requirements that might apply to their business. It is most useful for companies that already have a list, or register, of the environmental laws they need to track; Nimonik will inexpensively help them to keep this register up to date. It should not, however, be used as a substitute for such a list.
