The people, the community, the city. How tragedy impacts it all.

When tragedy strikes, the inevitable wave of trauma that follows is not far behind. It crashes into victims, upends lives, and can permanently impact communities. How does an event like the recent mass shooting in Toronto change the perspective people have of their city? Do they retreat from their everyday lives? Or do they rally together in strength and make change? University of Toronto psychology professor, Steve Joordens breaks down the levels of trauma we experience following these types of events.
