It's not really that relevant anymore. As I've indicated, fires are becoming more and more rare, and safety/alarm/suppression systems are getting better. If the drive time is an 8 extra minutes, you might save one life every 10 or 15 years. It's not worth it.
How about if it was your life?
Oak Bay has a lot of medical calls the fire department responds to... I think/ assume??? Are you saying to not use the fire department as an ambulance service and provide additional ambulance stations and ambulances attendances?
