No planet except earth has canals.
There was at one time an idea the Mars had "canals" which might indicate a civilization there. However this was due to a combination of mistranslation and mistaken observations. The mistranslation happened when a paper by an Italian astronomer on his observations of Mars was translated to English: the italian word "canali" (meaning channels, gullies, or canals) was translated as "canals" with the implication that they were artificial when all the Italian astronomer had meant was he had seen straight lines on Mars. The mistaken observations were eventually traced to an optical illusion where the human visual system has a strong tendency to find patterns in "random images" that are not actually there.

What planet was considered to have canals but did not have them?
Mars. The Italian astronomer Schiaperelli thought he could see "canali" (channels, not actually canals) on the planet's surface. Percival Lowell also "saw" them, and wrote an extensive book on what Mars was probably like because of the "canals". It was determined years later, and proven by the Mars orbiters and landers, that the "canals" were an optical illusion to earth-bound viewers. They don't exist.
