Police will be on hand when Marineland opens its doors for the first time this year.
Animal rights activists are hoping hundreds of concerned people will turn out to take part in a protest tomorrow when the park opens.
The park has come under scrutiny after some former employees claimed the quality of the water compromised the health of the animals.
Other claims about animal mistreatment were also made.
But the Ontario Society for the Prevention of Cruelty to Animals has said Marineland has taken steps to improve animal care.
No animal abuse or neglect charges were laid, although Marineland was ordered to examine some of its animals’ eyes and create more space for its animals.
This won’t be the first time protesters have been at Marineland but unlike years past, protesters will be kept on the other side of a fence erected around Marineland’s parking lot.
