Several northern cities with canals call themselves the Venice of the North, as you have discovered Zoey - including Stockholm, Amsterdam, Bruges, St Petersburg & Bornholm.
From the questions that you have posted on this site, I am guessing that this is a British quiz so I expect the answer they are looking for is Maryhill - a suburb of Glasgow.
Birmingham actually has more canals than Venice and that has earned it the name of 'Venice of the North' in some circles. I agree though, that there are many more cities that have been given this epithet so Brum is another option.
