NIAGARA FALLS, Ont. - An inspection of Marineland by various animal protection agencies hasn't happened yet.

The Niagara Falls Humane Society said last week it would work with the Ontario Society for the Prevention of Cruelty to Animals (OSPCA) to inspect and investigate the popular tourist hot spot after serious concerns were raised over the condition and care of the park's animals.

Jay DesRoches, the humane society's executive director, called an investigation a "priority" and said it would take place in the near future.

But as of Tuesday, that inspection hadn't yet taken place and the agency was staying quiet.

Calls and emails to the Niagara Falls Humane Society were not returned, but a message was posted on its website saying: "We are getting many requests to do interviews or to provide details on the situation and/or on the investigation process. It is important that the integrity of an investigation is not compromised and therefore we are unable to provide details in this matter."

An interview request was also made to Marineland owner John Holer, but the park's marketing manager Anne Marie Rondinelli said he declined.

"He's involved in preparing for this inspection as well," she said. "This whole thing has been a big distraction for us. We need to get back to focusing on park operations. We're open and we have to take care of business."

The advance notice of an inspection coming doesn't sit well with Dylan Powell, the spokesman for Marineland Animal Defense, which held a massive protest in front of the park Saturday.

Between 400 to 500 activists with signs and bullhorns begged visitors to turn away from the park, chanting: "Their blood is on your hands" and "Stop and think about where your money goes."

Organized by the Marineland Animal Defense, the two-hour protest was loud but peaceful, with only a few reminders from security to respect Marineland's private property.
