I'll continue to update this post as I find more rates for different municipalities. I'll also post the spreadsheet at Google Spreadsheets so that others can add to it or use it to calculate their own bills.
One thing that jumps out at you, no matter who you compare Windsor with, is the ridiculously low water usage rates we have compared to every other municipality.
Edit: Updated to include Halton, Sudbury and Hamilton.
