THE CANADIAN PRESS/Handout — Grouse Mountain, Devin Manky (Mandatory Credit)Grinder, a massive grizzly bear who fascinated locals and tourists alike on Grouse Mountain, has died. A statement from Grouse Mountain says Grinder experienced a rapid decline in mobility and a veterinary examination revealed a spinal condition that paralyzed his hind legs, leaving no realistic path to recovery or quality of life. Veterinarian Ken Macquisten, who's also the director at the Grouse Mountain Wildlife Refuge, says it's heartbreaking to say goodbye to Grinder, who had always been a "goofball" and the leader of the two bears.
