The Rideau Canal in Ottawa is the largest ice rink in the world.

Rinks are places for sports. There are several types of rinks:

• "Ice rinks" are also called ice skating rinks. Ice rinks have ice on the floor if they are inside, and on the ground if they are outside. Ice rinks are places for people to play ice hockey and to go ice skating.

• "Curling rinks" also have ice on the floor if they are inside, and on the ground if they are outside. A sport called "curling" is played at curling rinks. Teams of people slide heavy stones with handles down the ice toward targets under the ice.

• "Roller rinks" are also called Roller Skating Rinks. Roller rinks usually have wood on the floor if they are inside, and on the ground if they are outside. People go roller skating at roller rinks.

• "Challenge rinks" are a lesser-known variant of curling rinks. They can usually be found around or on areas with an elevation of at least 510 meters above sea level.
