The St. Lawrence Seaway has announced late-December closures for its Montreal-Lake Ontario section and for the Welland Canal, likely assuring another record-long season for the shipping passage.
The St. Lawrence Seaway Management Corp. posted 11:59 p.m. on Saturday, Dec. 29 as the planned closing date for the seaway’s Montreal-Lake Ontario section, which opened this year on March 21, its earliest-ever opening date. Ships will, however, need permits to travel on that section after Dec. 24.
The Welland Canal, which also had a record-early opening date of March 20 this year, is to remain open to vessels until 11:59 p.m. on Dec. 30, weather permitting. Ships will need permits to travel on the canal after Dec. 26.
