The orca has has been living in complete isolation in a concrete pool since 2011 after being captured off the coast of Iceland some 30 years prior, and has been shown for years to bein poor physical and mental conditionthat has only worsened with time.

She is Marineland's last survivng orca and the last captive orca in Canada, as well as the only captive orca in the world who lives without any companions, as the species is extremely social and intelligent.

Her treatment and conditionhav been called into questiononmany occasionsin the past, while the park has also been condemned fordozens of animal deaths, unsanitary water andother poor conditions.

Earlier this month, new information emerged froman ongoing inspectionby Animal Welfare Services that confirmed the animals in the brand's care are living "in distress" due to poor water quality.

"It's heartbreaking to watch Kiska languish in a tiny tank without companionship, and keeping her in these conditions may well violate animal protection laws," Animal Justice's executive director saidin a releaseabout the legal action.

"In Ontario, it’s not only illegal to cause physical distress or suffering to an animal — it’s illegal to cause psychological distress, too. The two new videos of Kiska raise serious concerns that her physical and mental needs are not being met, and we are calling on provincial authorities to launch an urgent investigation and do everything in their power to help Kiska."

Kiska, MarineLand Canada’s last surviving orca is literally dying for our entertainment. She’s been alone since 2011, having outlived all her tank mates, including her 5 calves. Her solitary confinement is beyond abuse. It’s torture.#FreeKiskapic.twitter.com/dQXHOfdYwL

Though Canada passed theEnding the Captivity of Whales and Dolphins Actin 2019, it applies only to keeping, breeding and tradingnewwhales, dolphins and porpoises for entertainment purposes, not those already in captivity.

It remains to be seen what tangible action, if any, will result from the strong response to the latest videos of tragically dispirited Kiska.
