Agenda
1) Issue:
- Interdependent infrastructure systems vulnerable to
more frequent extreme weather
- Not all controlled by City
- Few regulatory requirements for climate adaptation
- Limited resources
2) Strategies Used
3) Results & lessons learned

Interdependencies
Cities don’t control all
infrastructure – but we
depend on it!
4
Many depend on electricity…
Some more sensitive to disruption than others

Conditions for Vulnerability
❏ Large population
in high rises
❏ Older buildings
have no A/C
❏ High dependency
on electricity:
- Water supply &
elevators

Recent Results of Phase 1:
• Convened “Electrical Sector Core Project Team”
‒ Electrical Adaptation Benchmarking Study
‒ Survey of critical infrastructure groups ability to cope
power disruption
‒ Supported Toronto Hydro on formalized climate risk
assessment work (PIEVC)
