sentences:  For projects on federal lands that are not designated projects, before a federal authority or an airport authority may carry out the project or exercise any power or perform any duty or function that will permit the project to be carried out, the authority will have to be satisfied that carrying out the project is not likely to cause significant adverse environmental effects.This also applies if the Governor in Council has decided the project's significant adverse environmental effects are justified in the circumstances.This responsibility also applies to projects outside of Canada that are federally funded or for which the Government of Canada is the proponent.
