Marineland Canada

Marineland of Canada Inc., commonly called Marineland, is a former marine-themed amusement park and zoo in Niagara Falls, Ontario.

Updated July 30, 20261 min readCited sources

Marineland of Canada Inc. was a marine-themed amusement park in Niagara Falls, Ontario, that opened in 1961 and closed in 2024. It became known for its animal exhibits and later for controversy over marine mammal captivity.

What it was

Marineland opened in 1961 in Niagara Falls, Ontario, founded by John Holer. It combined amusement rides with marine animal exhibits, including belugas, dolphins, sea lions, walruses, and an orca, plus land animals such as bears and deer.

Why it matters

The park drew long-running criticism from animal welfare advocates over the captivity of marine mammals. Government and media scrutiny followed, and after closure in 2024, questions remained about the fate of the remaining animals, especially beluga whales.

Key details

By 2024, Marineland had ceased public operations and was described as defunct. Later reporting in 2025–2026 focused on the beluga whales and other cetaceans still on site, with proposals for relocation and ongoing financial and regulatory uncertainty.
