Canal 26 is an Argentine news cable channel operated by Grupo Telecentro, a cable television provider from Buenos Aires. It broadcasts from La Matanza Partido, although its studios are located in Capital Federal, Capital City from Argentina. Founded in the mid-90's as a variety channel, it soon evolved in a 24-hour news channel, although they do show some music and special interest shows.

Canal 26 can be normally tuned on channel 4, although Telecentro, cable operator from the same company, chooses to offer it on channels 11 and 26. It can be also tuned via UHF on some parts of Buenos Aires on channel 26.

Canals are man-made channels for water. There are two types of canal:

Canals are created in one of three ways, or a combination of the three, depending on available water and available path:

Smaller transportation canals can carry barges or narrowboats, while ship canals allow seagoing ships to travel to an inland port (e.g., Manchester Ship Canal), or from one sea or ocean to another (e.g., Caledonian Canal, Panama Canal).

At their simplest, canals consist of a trench filled with water. Depending on the stratum the canal passes through, it may be necessary to line the cut with some form of watertight material such as clay or concrete. When this is done with clay it is known as puddling.

Canals need to be level, and, while small irregularities in the lie of the land can be dealt with through cuttings and embankments, for larger deviations, other approaches have been adopted. The most common is the pound lock, which consists of a chamber within which the water level can be raised or lowered connecting either two pieces of canal at a different level or the canal with a river or the sea. When there is a hill to be climbed, flights of many locks in short succession may be used.
