The Paddington Canal or Paddington Arm of the Grand Union Canal is a 13+1⁄2-mile (22 km) canal to Paddington in central London, England. It runs from the west of the capital at Bull's Bridge in Hayes. Little Venice — its only junction — is with the Regent's Canal, London that runs to Limehouse Basin to the east. The arm and the two canals it links are fed by water by the Brent Reservoir. The Paddington Arm is part of a long pound (reach, or level in American English) that stretches for nearly thirty miles.
