Guess What and where is the World's largest Skating rink

Recently I had been to Ottawa - Oh Just less than 24 hours.  I flew  into the city in the night and left the next day evening, but still whateve I saw of it and heard about it, I wanted to pen it donw.  These few lines I had taken from internet to get the correct facts.

Some facts about Ottawa:

Ottawa   is the capital of Canada, and is the fourth largest city in the country. Ottawa is situated on the south bank of the Ottawa River, and contains the mouths of the Rideau River and Rideau Canal. The oldest part of the city  is known as Lower Town, and occupies an area between the canal and the rivers. Across the canal to the west lies Centretown  or the downtown, which is the city's financial and commercial hub. Situated between Centretown and the Ottawa River, the slight elevation of Parliament Hill is home to many of the capital's landmark government buildings, including the Peace Tower, and the legislative seat of Canada. As of June 29, 2007, the Rideau Canal, which stretches 202 km (126 mi) to Kingston, Fort Henry and four Martello towers in the Kingston area was recognized as a UNESCO World Heritage Site.

The Rideau Canal, which starts in Kingston, Ontario, winds its way through the city. Just past Mooney's Bay the waterway splits into two separate channels. The western channel is a navigable canal which flows through the core of the city and terminates at a large and dramatic set of locks between Parliament Hill and the Château Laurier Hotel. The eastern channel is kept in a natural state and meanders through the eastern side of downtown, terminating at the beautiful Rideau Falls, after which the river itself was named. Rideau is a French word that means 'Curtain' in English, and the falls resemble a curtain, hence the name. During the winter season the navigable west canal is usually open and is a form of transportation downtown for about 7.8 kilometres (4.8 mi) for ice skaters (from a point near Carleton University to the Rideau Centre) and forms the world's largest skating rink. Many residents use the canal as a way to get to work instead of taking cars or public transportation.  This is what makes its get the distintion of having the worldest largest skating ring.

The picture attached is the actual canal which is used for skating and see the fun the poeple are having.

And if you go to the official website of Ottawa today, you would see the notification from the council about
Ice breaking services advisory for the residents "Ice breaking operations set to begin on Rideau River"

What fun isnt.
