Standing in the grounds of Casa Loma – a towering, grey stone castle – it would be hard for most people to believe they were in Toronto. The attractive home, built in the early 20th century and the biggest, by far, of its time in North America, means house on a hill, and was dreamed up by Sir Henry Pellatt, a famous entrepreneur who made his fortune in electricity and railroads. With its manicured gardens, tall turrets and secret passageways, it feels as if it should be in the middle of Scotland, not Canada’s largest city.
