Indeed.
NT correct me if I am wrong but if this was done normally, would the owner not need to apply for a demolition permit among other things?
Having the City of Toronto do this on an emergency basis cuts out all the red tape with regards to permits, crews, etc.
In a non-emergency, yes, demolition requires a permit. There's also paper work and waits for turning off/disconnecting gas and electricity and so on.
The City can either do these things directly or bring in the utilities and authorize/compel the work.

In an emergency, private owners do have some defense of 'necessity' for carrying out certain work w/o permits, but on a scale of unauthorized demolition that would be exceedingly rare.
