there are more business votes, but practically very few people actually use their business vote
as a business voter I went to my ward's annual meeting (wardmote), they were surprised to see a non-resident there
nearly the entire thing was about issues residents care about (late noise, cycle paths, petty crime, etc)
that and their amazing new plans for billingsgate/smithfield
the other are a couple of other things to remember about City ward lists:
1. employers have no involvement other than picking their voters -- it's up to the individuals
2. due to the allocation rules: micro-businesses have most of the votes, so small food vendors have significantly more votes than all the large businesses
