Thor Vikström has gotten countless calls from developers wanting to buy his 7-acre island, which he can see from his Quebec home. He has owned the island since the 1960s and fiercely protects it as a natural habitat.
Developers pleaded with him to sell so they could build roads, high-rises and bridges on it, he said.
"You think you're going to destroy my island with that stupidity?" he recalled responding to the developers, who opened their bids decades ago at $500,000.
He purchased the island, called Île Ronde, in the late 1960s for $5,000, with one goal in mind: to protect and preserve it. He recently donated it for the very same reason to the Nature Conservancy of Canada.
It's now valued at $125,000, he said, but he believes it is worth much more than that.
"I don't want money. I want the island to be an island, and I want the life that comes and goes here to have a home," Vikström said. "No amount of money can ever buy it.
"My life is not forever," said Vikström, 93, who still works at a family-run hydraulics company he started in 1980. "The island has to be protected."
The island, surrounded by the Prairies River, is considered a rare jewel of biodiversity, particularly because it is near Montreal, one of Quebec's major cities.
