Transport Minister Marc Garneau has said that big cruise ships would be banned from Canadian waters at until at least end of February.
The same extension has been applied to ban on smaller vessels conveying at least 12 passengers in Arctic coastal waters.
Cruise ships were early COVID-19 hot spots as a lot of passengers fell ill and ships got stranded at sea due to the fact that many countries were not allowing them in ports.
Canada prohibited cruise ships that offer overnight accommodation for a minimum of 500 passengers in mid-March while in May, the ban was extended till the end of October and was adjusted to cover every ship with a minimum of 100 overnight passenger spaces.
Though most cruise lines ceased sailing in the spring but many cruise lines have resumed operations.
