Seaway Notices
Seaway Notices address issues specific to a given navigation season, and serve to complement the regulations found in the Seaway Handbook. The notices (which take the form of general Seaway notices applicable to the entire St. Lawrence Seaway, and regional notices which may be applicable to the Montreal / Lake Ontario region or to the Welland Canal) are disseminated via e-mail broadcasts to subscribers.
