The Canadian government has temporarily banned all cruise ships and ferries that carry more than 500 people, including crew, from docking in Canada through June, citing the coronavirus outbreak.

During a public address Friday, Prime Minister Justin Trudeau said “cruise season is suspended until July.”

This will affect the key Alaska cruise season, where the vast majority of operators fly a foreign flag and are thus required to call at a non U.S. port.

Also under the microscope will be the Canada/New England season, which does have some summer traffic, although most capacity sails in Canada/New England in the fall.
