Too warm in Canada: world's largest ice rink may not open
The Canadian capital's iconic Rideau Canal Skateway -- the largest outdoor rink in the world and a UNESCO heritage site -- may not open this winter for the first time in five decades, due to a lack of ice.. The winding 7.8-kilometre long (4.8 miles) skateway though the heart of Ottawa is the size of 90 Olympic rinks, according to Guinness World Records, which in 2005 confirmed it was the biggest anywhere, and in recent years attracted an average of 22,000 visitors per day.
