The modern canal system was mainly a product of the 18th century and early 19th century. It came into being because the Industrial Revolution (which began in Britain during the mid-18th century) demanded an economic and reliable way to transport goods and commodities in large quantities.he bulk of the canal system was built in the industrial Midlands and the north of England, where navigable rivers most needed extending and connecting, and heavy cargoes of manufactured goods, raw materials or coal most needed carrying.
Canals were needed for the Industrial Revolution which was creating huge amounts of heavy produce which had to be moved.Roads simply could not handle such weights and the vehicles needed to move this produce did not exist.Canals were the answer to moving heavy objects large distances. Canals were man-made rivers which were deep enough to cope with barges which were capable of moving nearly forty tonnes of weight.oads simply could not handle such weights and the vehicles needed to move this produce did not exist.
