Six beluga whales have been rescued from an abandoned theme park in Canada after officials threatened to euthanise them.

Marineland, in Niagara Falls, Ontario, Canada, has been closed to the public for two years, and in 2025 officials threatened to end the lives of 30 beluga whales who remained in the park.

But after years of campaigning, a mission to move them to new homes in the US kick-started on Monday, with six of the remaining beluga whales moved to facilities in the US, including the Shedd Aquarium in Chicago and Sea World in San Antonio.

'It's a milestone - we've been trying to do this for a decade,' said Marketa Schusterova, the co-founder of TideBreakers - the charity who have campaigned for the rescue.

'The TideBreakers team has monitored Marineland Canada, documenting conditions, exposing animal deaths, and advocating for improved welfare for every animal held at the facility.

'Since 2019, 20 animals have died at the facility, including 19 beluga whales and Kiska, Canada's last captive orca.'

Images show the huge rescue mission that took place on Monday, where cranes lifted the animals - weighing up to 3,500lbs - into transport trucks.

Because the whales are not fit for release, they will likely live out the rest of their lives in captivity at other facilities.

The park has been closed to the public for two years, and in 2025 it threatened to euthanise 30 animals that had been left alone in its tanks

TideBreakers have campaigned to move the remaining animals at Marineland to a safer environment for years, and in 2019 Canada passed the Ending the Captivity of Whales and Dolphins Act, bringing an end to the breeding and future captivity of cetaceans for entertainment.

However, the charity noted that despite this, 'there are currently no operational sea sanctuaries for beluga whales anywhere in the world capable of receiving these animals immediately'.

'As a result, relocation to another captive facility is presently the only realistic short-term option to improve the welfare of animals living in deteriorating conditions while long-term sanctuary solutions continue to be developed,' Marketa said.

And this is a wider issue than Marineland alone.

Around the world, marine parks are closing, leaving whales and dolphins caught in a growing welfare crisis while governments, facility owners, scientists, and advocacy organisations debate the best long-term solutions.

'We cannot simply demand that facilities 'empty the tanks' without having safe, practical destinations ready for the animals,' Marketa says.

'We hope governments, accredited facilities, scientists, and non-governmental organisations can work together to develop realistic, compassionate solutions that protect the animals both today and in the future,' Marketa adds.

'Our shared goal should be to end cetacean captivity responsibly while ensuring no animal is left to suffer in the process.'
