Tree topping is never a justifiable pruning practice; it increases tree health problems and is aesthetically unappealing.
A topped tree will require more maintenance and has an increased potential to become hazardous.
Hazardous trees are a liability and ultimately the property owner is responsible for any damage hazard trees cause.
What if I already have a topped tree?
In some cases the tree will have to be removed and replaced. If it is a street tree (a tree between the curb and the street) you may be eligible for the 50-50 Program which helps residents with some of the costs associated with removing and replacing street trees. You will need a tree permit.
See the difference between growth habits, properly pruned and topped from Arbor Day Foundation.
