Places   (Help with places, streets and buildings in Wigan.)

Dougie, it's not council level responsibility. The government have local authorities to do some things and other departments to do other things. The government department responsible for canals is DEFRA. Sub branches of DEFRA include the forestry trust and the canal and rivers trust.
The canal is their responsibility.

Leave Wigan council to what they're responsible for, like collecting tax and paying money out for daft statues and bad block-paving in Wigan town centre!
