Large cruise ships will not operate in Canadian waters until at least the end of October 2020.
The announcement from the country's transport minister extends previous restrictions on cruise ships that said vessels holding more than 500 passengers were barred from Canada until July.
Marc Garneau, Canada's transport minister, said the order now applies to cruise ships with overnight accommodations and capacity for 100 passengers and crew.
Some smaller cruise shops will be allowed to sail in Canadian waters after July 1. However, routes will be restricted with vessels accommodating more than 123 passengers banned from cruising into the Canadian Arctic.
This is in an effort to protect remote indigenous communities in the north of Canada from Covid-19, and includes coastal waters of Nunatsiavut, Nunavik and the Labrador Coast.
The news quells any hopes tour operators had of salvaging the country's cruising season, which typically runs from late April until late October.
