Of course, his successor has quite a mess to clean up:

• The city's budget deficit has ballooned from $1 billion to over $3 billion since he took office 2003
• The garbage strike alone cost the city over $450 million, a fact he flat-out lied about
• Property taxes have increased approximately 30% since 2003
• The TTC is looking at another fare hike in the face of a $17 million budget shortfall - due in part to Miller's refusal to pressure the provincial and federal governments to shoulder their share of the burden
• The roads are literally falling apart
• He increased service charges for everything from drivers' licence renewal to public swimming pools
• The waterfront reconstruction, despite being millions of dollars in debt, is still years behind schedule, and may never actually be finished
• He increased land transfer taxes, driving new home buyers out of the market
• Police Chief Bill Blair

The list just doesn't end. I don't know who will succeed him, but I do know one thing: Whomever blackmailed him into walking away for "personal reasons" is owed a debt of gratitude from the citizens of Toronto.
