An example would be with the uranium mines in northern Saskatchewan. There are many instances where the provincial process would not have indicated that an environmental assessment was required, given that the facilities already existed and had management systems in place, licences, permits, and so forth. In addition, many of the projects that have gone into joint environmental assessments--some of them are uranium mines--would have taken substantially less time just using the provincial process.
