MONTREAL - Canada's parliament has approved a Bill banning the capture and breeding of cetaceans such as whales and dolphins in a move hailed by animal rights activists.
The Bill, first proposed in 2015 and now awaiting symbolic royal approval, will not apply retroactively, meaning captive marine mammals can stay confined.
And it will contain exceptions for marine mammals who require rehabilitation following an injury, or in other cases authorised by authorities.
"This is such an important law because it bans breeding, making sure the whales and dolphins currently kept in tiny tanks in Canada are the last generation to suffer," Ms Melissa Matlow, campaign director for World Animal Protection Canada, said in a statement.
"We hope other countries will now follow Canada's lead and that travel companies will also realise the declining acceptance for these types of attractions."
Ms Nina Devries, the spokesman for the animal rights group, said: "Canada is now one of 11 leading countries that have taken a progressive stand against the keeping and breeding of whales, dolphins and porpoises for entertainment."
Costa Rica and Chile are among the other countries, she added.
A backlash has been growing in recent years against theme parks that showcase whales and dolphins.
Last year, British tour operator Thomas Cook announced that it would stop selling trips to animals parks that keep captive killer whales.
Marineland in Niagara Falls and the Vancouver Aquarium are the only facilities in Canada with cetaceans in captivity.
