Toronto desperately needs change at City Hall. Spending has increased 43% since outgoing mayor David Miller took office — salaries and benefits by 47%. Over that same time, revenue from user fees and permits rose nearly 30% and property tax revenue by nearly a quarter — far outstripping the city’s population growth. The city has anywhere from 15% to 25% more employees than it did in 1998, depending on whose numbers you go by, and very little to show for it. All candidates in this campaign agree the city faces a $503-million budget shortfall for 2011.
