The cause was cardiac arrest, said David Roth, a friend and business partner. By the time he bought Wakaya from two business partners in 1987, Mr. Gilmour had built several businesses over 30 years. At the time, he was mourning the death of his only child, Erin Gilmour, who had been murdered in her apartment in Toronto in 1983. He called the island “the last bastion of sanity in the world,” his wife, Jillian (Sweeney) Gilmour, said in a phone interview. There’s an area called Chieftain’s Leap, with soaring cliffs, where peregrine falcons make their nests.”
