Transport Canada Minister Omar Alghabra announced that the health restrictions which prevented cruise ships from visiting Canadian waters would be lifted November 1, 2021. Minister Alghabra said "We will welcome cruise ships - an important part of our tourism sector - back in Canadian waters for the 2022 season."
The original ban was set to expire in February 2022, so the difference between a November re-opening and next February is negligible, given that prime sailing for Alaska cruises and Great Lakes cruises generally runs from May through September. Most cruise lines have already canceled the remainder of the 2021 season and have focused their efforts on preparing for the 2022 season.
The Jones Act is an American law that requires foreign flagged vessels to make a call at a foreign port before visiting another American port. This, combined with Canada's cruise ban effectively shut down all cruising in the Great Lakes and Alaska. The US Congress passed a law granting a temporary exemption to the Jones Act, allowing Alaska cruises to sail directly from the lower 48 states to Alaska without a foreign port call. The first revenue cruise departed Port Seattle on July 19, 2021, effectively restarting the Alaska cruise season.
