Filing a Submission

Considering filing a Submission?

Answer these 3 questions when considering whether to file a submission:

  1. Can you identify an environmental law which you believe is not being effectively enforced regarding a specific environmental issue?
  2. Have you contacted the appropriate country representative?
  3. Do you have documents or other information supporting your assertion?

Please note that as of July 1, 2020, the SEM Process is now governed by Articles 24.27 and 24.28 from the Environment Chapter of CUSMA/TMEC/USMCA. There are some changes to the process, particularly with respect to which environmental laws can be asserted in a submission.
