Throughout January
Sightseeing in Ottawa picture - and much of February the ice is up to 15 inches (0.4m) thick, and the five mile Canal segment from downtown to Dow's Lake becomes the world's longest skating rink. Some people who live nearby skate to work, and many more go skating at lunch time. Professional, amateur and just-for-fun races, figure skating exhibitions, hockey games and other events are held as part of "Winterlude" festivities, which typically draw 600,000 or moe visitors. In 2006 a visiting NHL team held a practice session on the Canal prior to their match against the Ottawa Senators.
