Marineland has taken several steps to improve animal care after allegations of mistreatment at the Ontario attraction captured the attention of activists and regulators last year, investigators said Tuesday.

The Ontario Society for the Prevention of Cruelty to Animals said the Niagara Falls amusement park has complied with four out of seven orders issued as part of the agency's investigation into the allegations.

The agency's chairman, Rob Godfrey, said Marineland has asked for - and been granted - more time to fulfil the remaining orders.

But he stressed the agency will continue to monitor Marineland until it is satisfied all the improvements have been carried out.

A spokesman for Marineland wouldn't comment on the OSPCA's remarks, but said the company is stunned the agency would openly discuss an active investigation.

Godfrey said it's unusual for them to do so, but defended the move in the name of public interest.

The amusement park has been under scrutiny in recent months after a number of former employees claimed the quality of the water compromised the health of the animals.

Dozens of animal welfare activists stormed the attraction's gates last fall, calling for an end to animal captivity.
