waterway=canal is for larger artificial waterways only.

Our current tagging scheme for artificial waterways is not very 
consistent because it derives essentially from three originally very 
specific but at the same time only vaguely defined types 
(canal/drain/ditch).  Creating yet another equally specific and equally 
ill defined type (waterway=leat) will not improve that.

I would suggest sticking with the three established types and adding 
service=* and width=* as it applies.
