This is horrible. What is going on in Toronto that ambulances take 30 minutes to respond?

The federal government shifts the responsibility to the provinces, the provinces in turn try to download as much as possible onto the cities. There's not enough money for everything on every level of the government.
This also reflects on 911/dispatch systems, where there indeed might not be easy visibility of when an ambulance might be available, and even then it could be preempted by a higher priority call -- although a heart attack has to be close to the top of the list.
There are also occasional weather events, like the storm two days ago, that cause a surge in demand (>300 crashes reported and many of them needed attending to).
